Conversion between EOT and Fabry-Perot Resonances for Light Transmission Peaks through Two-Dimensional Metallic Slit Array

Payman Pahlavan

In this paper, two distinct light transmission peaks, named EOT and Fabry-Perot resonances, in slit arrays of metallic films are analyzed using mode matching method and simulated by FEM. These two resonances are known to be different in the transmission bandwidth, resonance frequency, and in the transverse magnetic field pattern in the resonance frequencies. However, it is observed herein that the variation in the structures thickness can convert EOT resonances to Fabry- Perot and vice versa.
