In this work, we propose novel structures of one-dimensional ternary planar photonic crystals (1D-TPPC) consisting of periodic unit cells of dispersive materials. The transfer matrix method (TMM) is utilized to investigate the propagation of the elec

We have used a new class of left-handed materials, which uses 3D nanospheres distributed in loops in the dielectric host material. These 3D nanospheres loops give rise to negative effective permeability and permeability at Terahertz (optical) frequen

In this work, we propose a novel compact bio-sensing platform based on defected photonic crystal waveguide for cancerous blood detection. The introduction of the defect layer in the middle of the structure leads to a sharp resonant peak in the photon

In this work, we introduce a novel structure of one-dimensional (1D) binary photonic crystals made of periodic stacks of a dielectric layer followed by alternating graphene and dielectric stripes. The transfer matrix method (TMM) is employed to inves
