Amirali Taghavi

Amirali Taghavi (M. Sc) graduated with a Bachelor's degree in Computer Hardware Engineering from the University of Tehran in 1996 and a Master of Science degree in Microwave Engineering from the Technical University of Munich (TUM) in 2008. He worked as a software developer and digital design engineer before moving to the analogue world and high frequency design. Taghavi has developed various circuits including high speed data acquisition systems, radio receivers and transmitters, and appliance control circuits. After working on carbon nanotube transistors at the Dresden University of Technology (TUD), he joined Langer EMV-Technik GmbH in 2018 as a hardware development engineer. Since then, he has been working on projects related to high-frequency probes, LNAs and fast high-voltage signal generators.

This article is the first part of a trilogy that aims to introduce a new paradigm in the measurement of specific electromagnetic shielding materials, namely shielding materials made from woven conductive threads. These articles highlight the shortcomings of common methods in the evaluation of such materials and introduce new approach and methodology to measure them. This new paradigm emphasizes characterization of shielding materials based on magnetic field rather than electric field. The new method introduces a measurement setup and lumped element model intrinsic to the material and independent from the measurement method.
