Effects of the negative index of a left-handed material on resonant transmission through Fabry-Perot resonators

Abstract

We study the effects of a negative index of left-handed material on the resonant transmission through Fabry-Perot (FP) resonators. Due to the negative optical length of a left-handed material layer, the resonant frequency of the metallic FP resonator with a left-handed material layer of -epsilon, -mu, and thickness d is higher than that of the resonator with a right-handed material layer of epsilon, It, and thickness d. The resonant transmission through a metallic FP resonator with a pair of the right- and left-handed material layers can be forbidden when the right- and the left-handed material layers are optically annihilated. We also discuss the effects of the negative index of a left-handed material on resonant transmission through a dielectric FP resonator.
