ARTIFICIAL LOW PASS MATERIAL

Abstract

According to Smith et.al [1990], a metamaterial composed of thin infinitely long metal rods arranged in a host medium with a periodic fashion exhibits “high pass” behavior. Therefore, it can be hypothesized that if infinitely long metal rods are replaced with finite sized thin metal rods, the resulting medium will exhibit “low pass” behavior. In this research, 3D electromagnetic simulation software HFSS is used to model host dielectric material with thin finite sized metal strips printed on it to prove the hypothesis. Simulation results shows “low pass” behavior of the simulated medium as expected. In addition to this, the factors affecting the cutoff behavior of the simulated low pass medium are also analyzed theoretically and numerically.
