By introducing losses or absorbers into the traditional FSS\, we can design both absorptive frequency-selective re flection (AFSR) and absorptive frequency-selective transmission (AFST) str uctures. I will first introduce the motivation behind the design of AFSR a nd AFST structures. A brief review of the state-of-the-art designs of AFSR and AFST structures will then be given. Design considerations will be pre sented to widen the absorption bandwidth and to reduce the reflection or t ransmission loss for the frequency band of interest. Practical examples wi ll befinally provided to demonstratethe performance of the designed AFSR a nd AFST structures with simulation and measurement results. Further resear ch topicsrelated to absorptive FSS will also be suggested in the end.\n\nC o-sponsored by: SBC05141B \n\nVirtual: https://events.vtools.ieee.org/m/26 9093 LOCATION:Virtual: https://events.vtools.ieee.org/m/269093 ORGANIZER:alexandreserres@dee.ufcg.edu.br SEQUENCE:3 SUMMARY:IEEE APS CHAPTER LECTURE -Distinguished Lecturer Dr. Shen Zhongxian g - Absorptive Frequency-Selective Structures URL;VALUE=URI:https://events.vtools.ieee.org/m/269093 X-ALT-DESC:Description: <br /><p>In this talk\, we will introduce the conce pt of absorptive frequency-selective structures\, which are different from the traditional frequency selective structures (FSS).
