The radial one-dimensional Euler equations are often rewritten in what is known as the geometric source form. The differential operator is identical to the Cartesian case, but source terms result. Since the theory and numerical methods for the Cartes

The stability of the contact interface for radial shock tubes is investigated as a model for explosive dispersal. The advection upstream splitting method with velocity and pressure diffusion (AUSM+-up) is used to solve for the radial base flow. To in

The planar spiral antenna's radiation integral is both conceptually and computationally complex. In the past, the far-field pattern has been found by either approximating the spiral's shape to make the computation tractable, or by using a numerical a

Free-space and rectangular waveguide techniques for determining the effective complex permittivity and, ultimately, the effective sheet impedance of an R-card using the forward transmission coefficient are presented. The advantage of using a transmis

No single scattering theory can be used to evaluate the scatter cross sections of surfaces with multiple scales of roughness. In this paper a two-scale unified full-wave approach is used to evaluate the backscatter cross sections for vertically and h

A harmonic Green's function solution for a magnetic line source above and below a flat interface between two chiral materials is derived. The solution is expressed in terms of the characteristic right and left circularly polarized waves. The harmonic

Metallic foams are being investigated for possible use in the thermal protection systems of reusable launch vehicles. As a result, the performance of these materials needs to be characterized over a wide range of temperatures and pressures. In this p

A Green's function approach for precisely computing the temperature and the three components of the heat flux in a rectangular parallelepiped is presented. Each face of the parallelepiped may have a different, but spatially uniform, boundary conditio

In order to derive full-wave solutions for electromagnetic wave scattering from rough interfaces between achiral media (free space for instance) and chiral media that satisfy generalized constitutive relations, it is necessary to employ complete moda

Steady periodic heating is an important experimental technique for measurement of thermal properties. In these methods the thermal properties are deduced from a systematic comparison between the data (such as temperature) and a detailed thermal model
