Judul	:	Effect of Filling-Factor on Transmittance of a Dielectric Slab Waveguide with Metallic Grating
Abstrak	:	The effect of filling factor on the transmittance characteristics of a slab waveguide with deposited metallic grating on its top is investigated by means of finite difference time domain method under uniaxial perfectly matched layer boundary condition. The system is assumed to be illuminated by a TM electromagnetic waves with oblique incidence. We studied the device transmittance for various angle of incident, while for the associated dielectric section in the grating we consider two different refractive indices. The result shows that the grating filling factor affects the device performance significantly. It is found that for certain values of filling factor and angle of incident, the difference of transmission for those two cases can be relatively large. We show this remarkable behavior is related to the surface plasmons interaction in the non-metallic section of the grating.
