Schmid & Partner Engineering AG (SPEAG) had developped the Dosimetric Assessment SYstem DASY in 1994. DASY has been improved continuously and all international standards were implemented. This made it the global market leader for SAR measurements (Specific Absorption Rate).
In 2000 SPEAG introduced SEMCAD, a Simulation platform for Electro-Magnetic Compatibility, Antenna design and Dosimetry. SPEAG is the only one offering test equipment and simulation tools for SAR. The common user interface simplifies the usage and reduces the time to become productive.
