چکیده

We study the defect-induced nonlinear transmission of a periodic structure created by alternating slabs of two materials with positive and negative refractive index. We demonstrate bistable switching and tunable nonlinear transmission in an unconventional band gap that corresponds to the vanishing average refractive index, and compare the observed effects for two different types of band gaps. © 2004 American Institute of Physics.

Tunable Defect Mode in One-Dimensional Ternary Nanophotonic Crystal with Mirror Symmetry

In this paper, the properties of the defect mode in the photonic band gap ofone-dimensional ternary photonic crystals containing high temperature superconductorlayer (SPCs) have been theoretically investigated. We considered the quasi-periodiclayered structures by choosing two order of ternary Thue-Morse structures with mirrorsymmetry. We investigated the transmission spectra of these structure...

Optical Bistability in Periodic Nonlinear Structures Containing Left Handed Materials

We study the transmission properties of a nonlinear periodic structure containing alternating slabs of a nonlinear right-handed material and a linear left-handed material. We find that the transmission associated with the zero-averaged refractive-index gap exhibits a bistable characteristic that is relatively insensitive to incident angles. This is in contrast to the nonlinear behavior of the u...

Defect modes and transmission properties of left-handed bandgap structures.

We analyze transmission of electromagnetic waves through a one-dimensional periodic layered structure consisting of slabs of a left-handed metamaterial and air. We derive the effective parameters of the metamaterial from a microscopic structure of wires and split-ring resonators possessing the left-handed characteristics in the microwave frequency range, and then study, by means of the transfer...

Effect of disorder on magnetic resonance band gap of split-ring resonator structures.

We investigated the influence of periodicity, misalignment, and disorder on the magnetic resonance gap of split-ring resonators (SRRs) which are essential components of left handed-metamaterials (LHMs). The resonance of a single SRR which is induced by the split is experimentally demonstrated by comparing transmission spectra of SRR and closed ring resonator. Misaligning the SRR boards do not a...

A Low Insertion Loss and High Selectiv- Ity Uwb Bandpass Filter Using Composite Right/left-handed Material

A novel bandpass filter (BPF) based on the composite right/left-handed (CRLH) material and 0◦ feeding structure is proposed. With multiple unit-cells cascaded, the new section comprises the series interdigital capacitors and the shunt short-circuited stub inductors in the symmetric configuration. The circuit is designed to be unbalanced, a tunable gap between left handed and right handed modes ...
