Schmid & Partner Engineering AG (SPEAG) is a Swiss company based in Zurich, Switzerland. SPEAG was founded in 1994 as a spin-off of the Department of Information Technology and Electrical Engineering (D-ITET) of the Swiss Federal Institute of Technology in Zurich (ETH Zurich). SPEAG develops numerical tools and manufactures instrumentation for assessment of radiofrequency (RF) radiation emited by wireless devices such as mobile phones, tablets, and laptop computers. SPEAG tools for measurement of electromagnetic (EM) radiation in the near- and far-field at frequencies from static to millimeter wavelengths are used by the wireless communications industry, research and development (R&D) departments, testing laboratories, government agencies, and regulatory bodies, as well as universities and research institutes. Exports account for around 99% percent of company revenues, and about 30% of the annual net revenue is reinvested in R&D.market products for testing the compliance of mobile communications devices with governmental safety limits.
SPEAG employs 50 – 100 people, and, together with its partner organizations the Foundation for Research on Information Technologies in Society (IT'IS), ZMT Zurich MedTech AG (ZMT), and TI Solutions AG, forms the Zurich43 (Z43) alliance.
History[edit]
SPEAG was founded on 20 December 1994 by Prof. Niels Kuster, Thomas Schmid, Kurt Schmid, Martin Schmid, Oliver Egger, and Klaus Meier. The main objective of the ETH spin-off was to further develop and commercialize the Dosimetric Assessment SYstem (DASY), a robot-based EM near-field scanning platform[1] used for testing the compliance of mobile communications devices with safety limits.[2]

In 1999, SPEAG became one of the founders of the IT'IS Foundation research institute, and remains a major source of the foundation's funding.
The 3rd generation scanner DASY3 was introduced by SPEAG in 1998, and DASY4 followed in 2002. Also during this period, various physical "phantoms" and tissue simulating liquids for filling the phantoms were developed as models of human anatomy to be used in combination with DASY for testing wireless device safety.[3] In December 2000, SPEAG released the Simulation Platform for ElectroMagnetic Compatibility, Antenna Design and Dosimetry (SEMCAD), a computer-aided design tool for the analysis and design of antennas embedded in complex EM environments. SEMCAD V2.0 was released in early 2003.
In 2001, the Executive Board of SPEAG founded NFT Holding AG, which purchased all shares from SPEAG's founders.
2005−2014[edit]
Updates to the DASY and SEMCAD product lines continue to be released. SEMCAD X Jungfrau was introduced in 2007,[4] followed by SEMCAD X Matterhorn in 2014. Additional product lines were added: iSAR and cSAR3D for the measurement of specific absorption rate (SAR); ICEy for automated EM near field scanning to evaluate EM compatibility and interference; the Dielectric Assessment Kit (DAK) for dielectric spectroscopy assessments; POsable Phantom for Electromagnetic sYstems Evaluations (POPEYE) whole body and body part simulators for radiofrequency (RF) testing and the Tissue Simulating Liquids (TSL) used to fill the phantoms; optical Time Domain Sensor (TDS) technology for measurements of electric and magnetic fields.
2015−[edit]
Updates to the DASY and SEMCAD product lines continue to be released. Currently, the version DASY8 is combined with cSAR3D-A as DASY8-3D. The latest SEMCAD release, SEMCAD X Matterhorn V20.2, operates on the same code base as Sim4Life, a computational life sciences platform marketed by partner ZMT. DAK-TL for dielectric measurement of materials in thin layers, including small samples of biological tissues or liquids, was launched in 2016. OH4VNA, a miniaturized optical head for cable-free testing of electrically small antennas, was introduced in 2018. In 2020, SPEAG released the Magnetic Amplitude and Gradient Probe System (MAGPy),[5] developed for safety compliance evaluations of wireless power transfer (WPT) systems. including for emerging 5G technologies.
