In this paper, we present a formulation of a finite‐difference vector beam propagation method for an isotropic open chiral slab waveguide. This method allows the analysis of wave propagation on a chiral slab waveguide whose structure varies along the propagating direction. Numerical results show that the proposed method works successfully. Using this method, we present two interesting examples of numerical calculation. One is the phenomenon that the first mode is converted to the third mode by a tapered chiral waveguide. The other is the phenomenon that the TE mode is converted to the TM mode by a straight chiral waveguide. © 1998 Scripta Technica, Electron Comm Jpn Pt 2, 81(1): 21–31, 1998.

“…Here TE and TM refer to TEand TMpolarized field components and K is the two-dimensional (in the plane of the interfaces) Fourier variable. This model covers symmetric and nonsymmetric dielectric slab chirowaveguides (see [9]), waveguides with ideally conducting or lossy boundaries, and corrugated boundaries, provided that the period of corrugations is much smaller than the wavelength.…”

“…The article utilizes a new approach, called the vector circiiit theory [ 161. This approach was introduced in solving wave guidance characteristics for a general set of chiral parallel-plate guides in [9]. The method is based on the vector circuit modeling of a chiral slab, in which the tangential fields on opposite sides of the slab are related through a chain dyadic matrix.…”

This article discusses electromagnetic wave propagation in chiral slab waveguides that are characterized by surface impedances of different types. The method applied makes use of the vector circuit theory and the related tangential field requirements on the slab surfaces. The method forms a coherent and solid approach to parallel‐plate waveguide analysis, since all cases considered can be solved from the same general eigenvalue equation. The theory is illustrated by numerical examples.

“…The concept of chirowaveguide was introduced in [4], [5], and the characteristics of a uniform planar chirowaveguide have been extensively investigated [6]- [10]. As a further step toward the design of versatile devices and circuits, the analysis of various discontinuities in chirowaveguides becomes significant.…”

“…In the analysis of the eigenvalue problem of the homogeneous planar chirowaveguide, a transverse equivalent transmission-line network is introduced [10], which indicates that the right circularly polarized (RCP) wave and the left circularly polarized (LCP) wave can propagate independently in the uniform regions and couple only at the interface. Although the eigenvalue problem can be treated by the vector transmission line network [6], the physical picture of the network used here provides additional clarity. In the longitudinal analysis, the electromagnetic-field problem is transferred into the building-block multimode network problem, from which the discontinuity structure is viewed as consisting of uniform waveguides, or building blocks, and junctions.…”

In this paper, we propose, develop, and implement an exact method to analyze the effect of discontinuities in open planar chirowaveguides. The method combines the buildingblock approach of multimode network theory with a rigorous mode-matching procedure. Both the scattering of discrete spectra surface-wave modes and the continuous spectra radiation and evanescent modes are discussed in this paper. The introduction of equivalent transmission-line networks brings new physical insight into the overall behavior of the discontinuities. Features such as symmetrical properties of the structure are also investigated. Based on the analysis, numerical results are displayed to demonstrate the usefulness of this approach and to discuss mode conversion and radiation characteristics of discontinuities.
