ABSTRACT
In this letter, the effect of resonant enhancement transmission in a Ge subwavelength periodic membrane is presented. The key idea is that the strong refractive-index modulation of the Ge subwavelength periodic membrane can support the excitation of three leaky mode resonances TE1,1, TE2,1, and TE3,0 in a reflection band, and every leaky mode resonance relates a transmission peak on its edge, thus the overlapping of the edges of these multiple leaky mode resonances can be tailored to create resonant enhancement transmission. Resonant enhancement transmission with single and double channels near λ=10.60 μm is designed to demonstrate this concept.
