Draft:Schmid & Partner Engineering AG

1995−2004

In 1999, SPEAG participated in the founding of the Foundation for Research on Information Technologies in Society (IT'IS),^[11][12] a nonprofit scientific research institute in Zurich, Switzerland. SPEAG continues to support IT’IS projects related to research in EM near-field assessment.

SPEAG introduced the 3rd generation scanner, DASY3, in 1998, followed by DASY4 in 2002. During this period, the company also developed physical dosimetry "phantoms" and tissue simulating liquids (TSL) to model human anatomy for use with DASY in wireless device safety testing.^[13] In December 2000, SPEAG released the Simulation Platform for ElectroMagnetic Compatibility, Antenna Design and Dosimetry (SEMCAD), a computer-aided design tool for antennas analysis in complex EM environments. The second version of SEMCAD was released in early 2003.

2005−2014

During its second decade, SPEAG continued to update its DASY and SEMCAD product lines. SEMCAD X Jungfrau was introduced in 2007,^[14] followed by SEMCAD X Matterhorn in 2014. The company also expanded its range of products to include iSAR and cSAR3D for the measurement of specific absorption rate (SAR); ICEy for automated EM near-field evaluation of EM compatibility and interference; the Dielectric Assessment Kit (DAK) for dielectric spectroscopy; POsable Phantom for Electromagnetic sYstems Evaluations (POPEYE) whole body and body part simulators for radiofrequency (RF) testing; optical Time Domain Sensor (TDS) technology for measuring electric and magnetic fields.

2015−2024

During SPEAG's third decade, the DASY platform was modularized to accommodate diverse dosimetric measurement needs. DASY Module SAR, designed for testing 4G and 5G devices, is used by the Cetacom Advanced^[15] testing laboratory for the wireless device testing program of the French radiocommunication agency Agences national des fréquences (ANFR)^[16]. The cSAR3D and DASY8 product lines were combined into DASY8 Module c3D (DASY83D), optimized for high-throughput testing. Additionally, new probes were developed^[17] for DASY Module mmWave to measure incident power density (IPD) at frequencies of up to 110 GHz. The technology for absorbed power density (APD) measurement in the 24 – 30 GHz frequency range – marketed as DASY Module APD – was developed through collaborative research projects with the ETH Zurich and the IT’IS Foundation – Module APD^[18] funded by Innosuisse and SEAWave funded by Horizon Europe.

DAK-TL, a device for dielectric measurement of materials in thin layers, including small samples of biological tissues or liquids, was introduced in 2016. In 2018, SPEAG launched the OH4VNA, a miniaturized optical head designed for cable-free testing of electrically small antennas. The Magnetic Amplitude and Gradient Probe System (MAGPy),^[19] developed for safety compliance evaluations of wireless power transfer (WPT) systems, including for emerging 5G and 6G technologies, was released in 2020 and subsequently integrated into Module WPT.

2025−

SPEAG has collaborated with the IT’IS Foundation to advance the split-cylindrical resonator method, developing the DAK-Resonator (DAK-R), a multi-frequency resonator cavity system for dielectric measurements at frequencies of 10, 17, 26, 35, and 45 GHz. This system supports broadband measurements used in research and development as well as quality assurance in the wireless, automotive, and medical device industries.

Dosimetric Assessment SYstem (DASY)

The current version of SPEAG's DASY robot-based scanning platform, DASY8, is available with modules optimized for specific applications, including testing of SAR, APD, IPD, and hearing aid compatibility (HAC).

The system is used internationally by testing laboratories – for example, USA-based CETECOM Inc. and Industrial Inspection & Analysis, Inc. (IIA), Innovation, Science and Economic Development (ISED) in Canada, IB-Lenhardt AG in Germany, Testilabs Oy in Finland, to evaluate the compliance of mobile communications devices with regulatory safety standards.

Simulation Platform for ElectroMagnetic Compatibility, Antenna Design and Dosimetry (SEMCAD)

SEMCAD is a computer-aided design tool used in the development and analysis of antennas. The latest release of SEMCAD, version X Matterhorn V20.2, shares the same code base as Sim4Life, a computational life sciences platform marketed by SPEAG's partner ZMT. SEMCAD has effectively merged with Sim4Life.

cSAR3D

cSAR3D is a system based on vector array technology for rapid measurement of SAR of wireless devices for evaluation of compliance with regulatory safety standards.^[20]

Dielectric Assessment Kit (DAK)

SPEAG's DAK) product line is used for measurement of dielectric parameters, including permittivity, conductivity, and loss tangent over the frequency range from 4 MHz to 67 GHz for applications in the telecommunications, automative, electronic, chemical, food, and medical industries.

Phantoms and tissue simulating liquids (TSL)

Phantoms are physical models of the human body that are used in testing to represent the dielectric properties of humans for testing over frequencies from <10 MHz to >100 GHz.. SPEAG produces both whole body – the POsable Phantom for Electromagnetic sYstems Evaluations (POPEYE) – and partial body EM phantoms for over-the-air (OTA) performance evaluation of wireless devices that are mounted on or operated close to the body. The phantoms are filled with tissue simulating liquids, also produced by SPEAG, that match tissue parameters over a target frequency range.

Magnetic Amplitude and Gradient Probe System (MAGPy)

SPEAG's MAGPy probe system was developed in a collaborative EURAMET project funded by the European Union.^[21] MAGPy is used to demonstrate compliance of WPT systems – such as for charging electric vehicles (EVs) – that operate at frequencies of 3 kHz–10 MHz with national regulations and international safety standards. Testing laboratories, for example Verkotan Oy^[22] in Finland, use MAGPy to evaluate compliance of WPT systems.
