“…If the impedance tensor is known, we now have enough information to solve numerically for a dispersion relation. Equations (13), (15), and (16) can be inserted into (10) to get a dispersion relation as (19) where is the speed of light in a vacuum. We can solve (19) numerically to get the dispersion relation between the frequency and wavenumber of the surface wave .…”

“…Isotropic dielectric slabs are studied in many textbooks (e.g., [18]). Anisotropic slab waveguides have been studied using mode analysis [19] and also using ray optics [20]. By applying the ray optics model to a surface structure, we can predict the dispersion relation for a structure with arbitrary dimensions and impedances in either the guiding or exterior regions.…”

A surface waveguide structure is studied using a theoretical model and simulated using Ansoft HFSS. A tensor impedance surface is surrounded by two lower impedance surfaces on a plane. Surface waves are guided losslessly within the inner region as long as it has higher impedance than the outer region. A theoretical model is proposed which predicts the dispersion relation of the waveguide using a ray optics method. Our tensor impedance surface theory can also predict the dispersion of scalar impedance surfaces. The theory and simulation show agreement for scalar and tensor impedance surfaces. Two applications of tensor impedance surface waveguides are presented.

“…Assuming that the wave propagates in the direction, we insert and into Maxwell's equations. In the case of full anisotropy (a full tensor ) it is not possible to split the problem into a pure TM and a TE part and the modes will be hybrid in nature [40]. Separation is only possible when the elements and are zero.…”

Abstract-The accurate analysis of optical waveguides is an important issue when designing devices for optical communication. Waveguides combined with liquid crystals have great potential because they allow waveguide tuning over a wide range using low voltages. In this paper, we present calculations that combine an advanced algorithm for calculating liquid crystal behavior and a finite-element mode solver that is able to incorporate the full anisotropy of the materials. Calculation examples demonstrate the validity of our program.Index Terms-Finite-element mode solver, nematic liquid crystal, optical waveguides.

“…We show that the mode properties are closely dependent on the operating frequency ω 0 of the slab waveguide. Furthermore, the mode cutoffs are analyzed under the assumption that the ratio of slab thickness d to free-space wavelength λ 0 , defined as the normalized frequency in [19], is only determined by the slab thickness d.…”

Abstract-The characteristics of the guided electromagnetic wave propagation through a slab waveguide of uniaxially anisotropic dispersive metamaterial are investigated. Taking the cold plasma media model with ω mpz < ω mp⊥ < ω ep⊥ as an example, the mode classification established in terms of the operating angular frequency ω 0 of the slab waveguide. The results indicate that the mode properties are closely dependent on the frequency. When ω 2 mpz < ω 2 0 < ω 2 mp⊥ there are infinite guided modes. It is also found that when ω 2 em < ω 2 0 < ω 2 mpz , there may be multiple solutions of the propagating mode with imaginary transverse wave number in a slab waveguide with thickness less than a certain value.
