Abstract :
Unlike most of the previous work that has been devoted for enlargement of omnidirectional gap (OBG) that originates from Bragg scattering, we address enlargement of zero-effective-phase (zero-ϕ) gap that gives rise in one dimensional photonic crystals (1DPCs) that contain alternating single negative materials. In this article, we propose a new structure by introducing thin unmagnetized plasma layer between the two single negative materials in each period. The new structure is named ternary plasma PCs (TPPCs). The influences of plasma thickness, plasma frequency and collision frequency on the gap width are discussed. Numerical results show that the TPPCs structure has wider OBG gap than that of the binary PCs counterpart. Moreover, the gap width is continually enlarged by tuning the plasma layer parameters. The proposed structure helps improving filters, switches, and other devices in the microwave range.
