The Features of the Characteristics of Artificial Magnetic Conductors Based on Band-Stop and Band-Pass Frequency-Selective Surfaces

详细

Artificial magnetic conductors (AMCs) based on band-stop and band-pass frequency-selective surfaces (FSSs) have been considered. Analytical expressions relating the AMC characteristics (position and operating bandwidth) and the FSS characteristics (resonance frequency and quality factor) have been obtained. Numerical calculations for specific FSS structures (with square and dumbbell-shaped slots) confirmed that the AMC characteristics can be estimated using analytical expressions. It has experimentally been proved that the AMC characteristics can be controlled by varying the FSS resonance frequency.
