wave guides

Principle of operation

Waves in open space propagate in all directions, as spherical waves. In this way they lose their power proportionally to the square of the distance; that is, at a distance R from the source, the power is the source power divided by R2. The waveguide confines the wave to propagation in one dimension, so that (under ideal conditions) the wave loses no power while propagating.

Waves are confined inside the waveguide due to total reflection from the waveguide wall, so that the propagation inside the waveguide can be described approximately as a "zigzag" between the walls. This description is exact for electromagnetic waves in a hollow metal tube with a rectangular or circular cross section.

field visit

Statement of American president just after the Second World War was while addressing to the nation when America was passing through worst financial crisis.

                                                                                      My fellow American citizen “ THANKS GOD WE ARE PASSING THROUGH THE FINANCIAL CRISIS NOT OF MORAL. AS LONG AS MORAL IS WITH US WE WILL OVER-COME THIS CRUNCH”. Now his words come true.

Therefore field visit is the practical form of education. Which makes our self reading to import following essential knowledge to our students:-

              IMPORTANCE OF FIELD VISIT

1. For Practical Education 2. All round development of students 3. To know the etiquette of life 4. To know the sorrow and pain of society 5. To know the responsibilities toward society 6. To know the importance of Ecology 7. To face with adversity of life 8. To know different species of animals, plants etc 9. To develop the ethical sentiment 10. To re-inculcate the love of mother-land 11. To know the different types of culture and tribes

fiber-optic cables

Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.File:Fiber-optic-fiber-edit.jpg Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.

If you look closely at a single optical fiber, you will see that it has the following parts:

   * Core - Thin glass center of the fiber where the light travels
   * Cladding - Outer optical material surrounding the core that reflects the light back into the core
   * Buffer coating - Plastic coating that protects the fiber from damage and moisture

Hundreds or thousands of these optical fibers are arranged in bundles in optical cables. The bundles are protected by the cable's outer covering, called a jacket.

Optical fibers come in two types:

   * Single-mode fibers
   * Multi-mode fibers

Single-mode fibers have small cores (about 3.5 x 10-4 inches or 9 microns in diameter) and transmit infrared laser light (wavelength = 1,300 to 1,550 nanometers). Multi-mode fibers have larger cores (about 2.5 x 10-3 inches or 62.5 microns in diameter) and transmit infrared light (wavelength = 850 to 1,300 nm) from light-emitting diodes (LEDs).

Some optical fibers can be made from plastic. These fibers have a large core (0.04 inches or 1 mm diameter) and transmit visible red light (wavelength = 650 nm) from LEDs.

How Does an Optical Fiber Transmit Light?

Suppose you want to shine a flashlight beam down a long, straight hallway. Just point the beam straight down the hallway -- light travels in straight lines, so it is no problem. What if the hallway has a bend in it? You could place a mirror at the bend to reflect the light beam around the corner. What if the hallway is very winding with multiple bends? You might line the walls with mirrors and angle the beam so that it bounces from side-to-side all along the hallway. This is exactly what happens in an optical fiber.

The light in a fiber-optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances.

However, some of the light signal degrades within the fiber, mostly due to impurities in the glass. The extent that the signal degrades depends on the purity of the glass and the wavelength of the transmitted light (for example, 850 nm = 60 to 75 percent/km; 1,300 nm = 50 to 60 percent/km; 1,550 nm is greater than 50 percent/km). Some premium optical fibers show much less signal degradation -- less than 10 percent/km at 1,550 nm.

Your contributed article, Definition of electronics

If this is the first article that you have created, you may want to read the guide to writing your first article.

You may want to consider using the Article Wizard to help you create articles.

Hello, I noticed that you recently created a new page, Definition of electronics. First, thank you for your contribution; Wikipedia relies solely on the efforts of volunteers such as you. Unfortunately, the page you created covers a topic on which we already have a page - Electronics. Because of the duplication, your article has been tagged for speedy deletion. Please note that this is not a comment on you personally and we hope you will continue helping to improve Wikipedia. If the topic of the article you created is one that interests you, then perhaps you would like to help out at Electronics - you might like to discuss new information at the article's talk page.

If you think that the article you created should remain separate, contest the nomination by clicking on the button labelled "Click here to contest this speedy deletion" in the speedy deletion tag. Doing so will take you to the talk page where you can explain why you believe the page should not be deleted. You can also visit the page's talk page directly to give your reasons, but be aware that once a page is tagged for speedy deletion, it may be removed without delay.

I dare say you do not have the 4 days yet, see: English Wiki user accounts that are more than four days old and have made at least 10 edits are considered autoconfirmed. However, users with IPBE editing through the Tor network are subjected to stricter autoconfirmed thresholds: 90 days and 100 edits.

Your edits to articles

Most of your edits to article space are being reverted by other editors. Your edits are either wrong, inaccurate, or not appropriate to that article. I advise you to stick to making suggestions on talk pages for now until you learn more about how things work here. Please note in particular the following points:

• Do not sign in article space - only on talk pages.
• Use the search function to look for articles with similar names before creating a new one.
• Do not write information on disambiguation pages that belongs in articles.
• Provide references for any new information you insert. Doing this will verify that the information is correct and it is less likely to be deleted.

Proposed deletion of Book:ELECTRONICS DUMP AN ENCYCLO-PEDIA:- 1) NEYAZ KHAN 2) VEENA NARAYANKAR 3) SHAIKH HAQUE MOBASSIR

The book Book:ELECTRONICS DUMP AN ENCYCLO-PEDIA:- 1) NEYAZ KHAN 2) VEENA NARAYANKAR 3) SHAIKH HAQUE MOBASSIR has been proposed for deletion because of the following concern:

Contains only three articles; title makes little to no sense; subject relates to electronics but is not clearly specified; possible test page based on creator's other edits.

While all contributions to Wikipedia are appreciated, books may be deleted for several reasons.

You may prevent the proposed deletion by removing the {{dated book prod}} notice, but please explain why in your edit summary or on the book's talk page.

Please consider improving the book to address the issues raised. Removing {{dated book prod}} will stop the proposed deletion process, but other deletion processes still exist. The speedy deletion process can result in deletion without discussion, and the miscellany for deletion process allows discussion to reach consensus for deletion.
