RCS of Large Bent Waveguide Ducts from a Modal Analysis Combined with the Kirchhoff Approximation
TL;DR: In this article, a fast method to predict the monostatic radar cross section (RCS) in high-frequency of a cavity, which can be modeled as a succession of bent waveguides of the same cross section and stuffed by a perfectlyconducting termination, is presented.

On finite element implementation of impedance boundary conditions
I. D. Mayergoyz,G. Bedrosian +1 more
TL;DR: In this paper, the scalar magnetic potential formulation of 3D eddy current problems with small skin depths is reduced to a weak Galerkin form and the finite element discretization of this form results in two (volume and surface) "stiffness" matrices.
LEGO : linear embedding via Green's operators
A.M. Water,van de +1 more
TL;DR: In this article, a modular modeling technique called linear embedding via Green's operators (LEGO) is proposed, which is a diakoptic method based on the Huygens principle, involving equivalent boundary current sources by which simply connected scattering domains of arbitrary shape may be characterized.

An FEM approach with FFT accelerated iterative robin boundary condition for electromagnetic scattering of a target with strong or weak coupled underlying randomly rough surface
Peng Liu,Ya-Qiu Jin +1 more
TL;DR: In this article, the authors present a numerical description for the scattering mechanism associated with strong or weak coupled interactions of a volumetric target at various altitudes above randomly rough surface, and the functional dependence of bistatic and back-scattering from the target above rough oceanic surface upon the target altitude, incident and scattering angle, etc., are numerically simulated and discussed.

Inferring rough surface parameters from average scattering data using approximate scattering models: 1. Gaussian spectrum
Roger Marchand,Gary S. Brown +1 more
TL;DR: In this paper, it is shown that the quasi-specular model is limited by multiple scattering and diffraction due to surface curvature, and the effects of polarization and the role of the surface dielectric constant are examined.
