Electromagnetic-material characterization is the process of determining the permittivity and permeability of matter. One of the predominant schemes utilized for computing these constitutive parameters is the Nicolson-Ross-Weir (NRW) algorithm. In thi

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

The impulse response of a conductor-backed lossy slab is evaluated analytically. It is shown that the impulse response consists of a specular reflection from the interface between free-space and the dielectric slab during the early-time period, and a

In this paper, the discrete principal-mode propagation constant of an imperfectly-conducting stripline field applicator is investigated. Specifically, a complex correction to the ideal (i.e., perfectly-conducting) propagation constant is sought using

A new ultra-wideband technique to detect a sea-skimming missile in a sea-surface clutter background is presented. This technique, based on the E-pulse concept, is shown to be effective in maximizing the target to clutter ratio. Results using both mea

The nature of the current on a general multilayered printed-circuit stripline structure excited by a delta-gap source is investigated. The current is obtained through the construction of a semianalytical three-dimensional (3-D) Green's function, whic

The time-domain image reconstruction problem can be formulated as a sinogram recovery problem. The sinogram recovery problem is to find a complete sinogram based on the measured incomplete sinogram. In this paper, we solve the sinogram recovery probl

The cepstral analysis technique may be used to recover a transient signal using only the spectral magnitude for a class of signals known as minimum phase. This paper considers the use of cepstral analysis in conjunction with the E-pulse method for ta

The E-pulse technique has been applied in the past to both the early- and the late-time components of a transient radar response. While the late-time E-pulse technique uses aspect-independent waveforms, the early-time E-pulse technique requires a sep

Two correlative radar target discrimination schemes using the transient and spectral scattered-field responses are proposed. These schemes use time-domain and frequency-domain methods to reduce the amount of data that must be stored for each anticipa
