摘要：Antenna or OTA measurements are blind. Knowing the detailed implementation of the device under test is not needed to realize them. They even include all production tolerances that might impact performance. However, measurements are limited to canonical test environments, e.g. in anechoic chambers. Simulations, on the contrary, can give access to electromagnetic fields in practically any scenario. Yet, simulations are only as good as the knowledge of the very details of the radiation source. What if one could unite the two and benefit from the combined strengths of experimental and numerical techniques? This talk shows how to enable this with the augmented OTA approach, involving the creation of an antenna digital twin, based on actual measured data. Practical applications are demonstrated, including field characterization inside the car and EMF assessments with virtual human models.
报告人简介：
Dr. Derat received the engineering degree from SUPELEC in 2002 and a Ph.D. degree in physics from University of Paris XI with honors in 2006. From 2002 to 2008, he worked at SAGEM Mobiles as an antenna design and electromagnetics research engineer. In 2009, he founded ART-Fi, which created the first vector-array Specific Absorption Rate measurement system. Dr. Derat operated as the CEO and President of ART-Fi, before joining Rohde & Schwarz in Munich in 2017. He is now working as Senior Director for Systems Developments and Project Implementations, covering Electromagnetic Compatibility, Over-The-Air, and antenna test applications. Dr. Derat is a Senior Member of the Antenna Measurement Techniques Association (AMTA) and the author of more than eighty scientific conference and journal papers, as well as an inventor on more than forty patents, with the main focus in antenna systems near- and far-field characterization techniques.
