The nondestructive characterization of in situ conductor-backed media is an important task for many commercial and military applications. These and similar applications may require completely nondestructive and noncontact free space material characte

This work demonstrates the use of genetic algorithms (GA) to perform electromagnetic characterization of dielectric materials. The characterization process entails that the GA generates candidate solutions of the permittivity; these solutions are the

The feasibility of using the E-pulse technique to identify the values of a resistance card (R-card) contained within a material stack is demonstrated. The late-time response of a material stack is modeled as a resonance series and an E pulse is const

Electromagnetic material characterization is the process of determining the complex permittivity and permeability of a material. Rectangular-waveguide measurements involving frequencies greater than several gigahertz require only a relatively small t

The feasibility of using the E-pulse technique to diagnose changes in the properties of simple layered materials is undertaken. Numerical results for a conductor-backed lossy slab and a Salisbury screen show that changes in permittivity, conductivity

This paper reports on the measured electromagnetic properties of dry and water saturated basalt rock over a frequency range of 1-110 GHz. Tests were conducted in standard waveguides below 12 GHz and with free-space systems above 12 GHz. The basalt us

[1] The electromagnetic characterization of layered materials is often performed using reflection-only measurements, and through the years several different techniques have been developed to accomplish this both in the laboratory and in situ. It is s

A general technique for calculating the propagation characteristics of a waveguide with arbitrary cross-sectional shape loaded with a circular dielectric rod is presented. The waveguide fields, which are represented as a sum of functions satisfying t
