Computer Code and Analysis Tool Development
Metatech has extensive expertise in the development of computer codes and analysis tools to support a constantly expanding range of problems. Much of this work involves special purpose applications. Computer codes and analysis tools have been developed to perform calculations in all areas of electromagnetic environmental effects including EMC and nuclear EMP.

Examples include time and frequency domain transmission line codes, special purpose codes tailored to geomagnetic storm studies, and calculational techniques which provide 3D outputs for GTEM studies.

PRODUCTS

The Metatech Commercial Products Division (CPD) has recently been spun off from Metatech as a new corporation, Quell. Metatech CPD developed a unique line of EESeal(tm) EMI filters and transient suppressors. The EESeal(tm) provides EMI protection and an environmental seal. It is designed to easily slip between any pair of mating connectors and can also be readily removed and reinserted. Once installed the EESeal(tm) shunts high-frequency electrical signals to the shell or to any preselected pin of the connector. 

Custom configurations, connector types, colors, sizes and electric specifications are available. Rapid prototyping is offered (within days) to support compliance testing.

Measured frequency attenuation characteristics of several EESeal(tm) filters are shown below for different capacitor values; the performance of a 5000 pF 9 Pin DSub filter is also shown for an IEC 61000-4-4 electrical fast transient waveform.
