Multichannel and omnidirectional transparency in periodic metamaterial layers

Abstract

Multichannel and omnidirectional transmission can be realized in one-dimensional periodic metamaterial layers, where double-negative materials and single-negative materials are alternately stacked. The proposed structures can produce as many resonance transmission modes as desired by adjusting the number of the periods. Such transmission modes with perfect transmission are robust against incident angles and polarizations. The frequencies and frequency intervals of these modes can be tuned by changing the thicknesses of the metamaterial layers. Composite right/left-handed transmission lines with lumped elements

Broadband phase retarder based on one-dimensional photonic crystal containing mu-negative materials

“…The angular frequency ω is in units of gigahertz. Such dispersion can be realized in special metamaterials using composite right/ left-handed (CRLH) transmission line by periodically loading lumped-element series capacitors and shunt inductors [24][25][26][27][28]. In the following calculation, we choose ε 1 3, μ 1 1, ω mp 10 GHz.…”

Generalization of transfer matrix method for bi-gyrotropic double-negative magnetic materials in order to use them in multilayer structures

“…In recent years, many studies with a variety of purposes have been made in the field of employing DNGs in multilayers and photonic crystals (PCs) [8,17,[25][26][27][28][29][30][31][32]. On the other hand, multilayers containing magnetic materials or magnetophotonic crystals (MPCs) have attracted considerable attention for their applications in MO devices.…”
