Adaptive Frequency Selective Surface with ring slot units
2007 International Symposium on Electromagnetic Compatibility, 2007Single layer and double layer adaptive FSS with ring slot units has been investigated in this paper. Ring slot FSS acts like band-pass filter. It can be used in antenna radomes. Lumped-element devices are loaded on the periodic units. Resonant frequency of the FSS depending on the lumped-element' capacitance could shift in a specified frequency band ...
