A formulation of the impedance boundary condition (IBC) is derived, which can be used in split-step parabolic wave equation solvers to accurately represent an interface with arbitrary dielectric properties. The approach relies on ensuring that the pl

Arrays of spiral resonators are used in the design of frequency-selective surfaces operating in the frequency range 2-18 GHz. The transmission spectrum of linearly polarized radiation incident on each array exhibits a multiplicity of resonance featur

In order to reliably predict long-range radar coverage within an ocean environment, one must accurately account for the effects of ocean roughness on radar propagation. The method known as the Miller-Brown approximation is a widely used technique for

The numerical simulation of long-distance, over-terrain propagation of electromagnetic waves has received considerable attention due to its strong impact on radar and communication technology. One highly desirable feature of the methods currently use

The problem of rough surface scattering and propagation over rough terrain in a ducting environment has been receiving considerable attention in the literature. One popular method of modeling this problem is the parabolic wave equation (PWE) method.

This paper describes the ducted ocean surface scattering integral equation routine (DOSSIER). DOSSIER is a numerically-efficient high-fidelity numerical model for calculating scattering from partially-submerged targets in ducting environments. The mo

We derive a Luneburg-Kline (GK) asymptotic series representation for wave propagation in a one-dimensional (1-D) continuously inhomogeneous medium. We set the solution up so that the classical phase function common to the Wentzel, Kramers, Brillouin,
