Guided Modes in a Waveguide Filled With a Pair ofLayers, Doublepositive D P SAlù, AndreaEngheta, Nader
Here we present the results of our theoretical analysis for guided modes in parallel-plate waveguides filled with pairs of parallel layers made of any two of the following materials: (1) a material with negative real permittivity, but positive real permeability (epsilon-negative); (2) a material...
We investigate the interactions of three transverse modes in a periodic waveguide.Three mode resonances result in the splitting of the traditional forbidden band.We find the transparency of the forbidden band to a single high-order mode.The transmission losses of two ducts illustrate the transparencies...
We study Dyakonov surface waveguide modes in a waveguide represented by an interface of two anisotropic media confined between two air half-spaces. We analyze such modes in terms of perturbation theory in the approximation of weak anisotropy. We show that in contrast to conventional Dyakonov surface...
/(蔚-1)1/2 corresponding to the hard wall condition, the TE eigenmode spectrum of the waveguide contains an infinite set of new non-uniform quasi-TEM modes with different transverse propagation constants in the empty part and identical longitudinal propagation constants equal to the wavenumber k....
Electromagnetic mode conversion in photonic crystal multimode waveguides A photonic crystal waveguide having multiple guided modes, the waveguide comprising: a dielectric confinement region surrounding a waveguide axis, the confinement region comprising a photonic crystal having at least one photonic band gap...
