Abstract
AbstractIn this simulation work, the optical transmission through a 1DTPS considering Si, metamaterial, and SiO2 with different thicknesses for Gigahertz device applications is studied. This discusses tunable band characteristics of the ternary periodic structure with variations in metamaterial thicknesses and incident angle, for TE as well as TM mode, and shows an omni‐directional application. It is noted that the transmission decreases in TE mode with increases in the metamaterial thickness, whereas increases in TM mode. Also, the transmittance in TE mode decreases on increasing the angle of incidence, whereas that increases for TM mode. Hence, it can be mentioned that the structure is a good transmitter of TM waves. The two PBGs increase with increase in the incident angle, for the TE mode; while in TM mode, the first PBG behaves in reverse manner and becomes narrow. For both cases of s and p waves, the PBGs exhibit blue shift with increase in the incident angle. It is to mention that a widen PBG region in the range 6–10 GHz in the first band is common in TE and TM modes at all incident angles, and hence the TPS shows the features of omni‐directional reflector. Such kinds of PCs enable better ideas in designing tunable microwave devices as well as ODR based devices like solar cells.
