In this work, Radio Frequency (RF) electromagnetic (EM) energy coupled into a human body model carrying a Manpack radio is investigated using the finite-difference time-domain (FDTD) method. A human body model consisting of twenty-three tissue groups is used to accurately represent the human body anatomy. The Specific Absorption Rate (SAR) and conduction current magnitudes are calculated for the cases...
In this paper we develop a model for the RCS of an open ended rectangular cavity with a partial floor, as in Fig. 1. The purpose is to gain further understanding of the RCS of aircraft cockpit-like structures. This is an extension of previous work for a PEC floor cavity in the sidewall of a finite cylinder [1].
This paper demonstrates the suitability of ray optics in conjunction with the Huygen's principle for EM simulations of UWB through-wall radar imaging. In the proposed scheme, targets are represented by their Huygen's equivalent currents, and walls are modeled by using a dielectric flat-plate formulation. The geometrical optics (GO) method is used to account for both the incidence and the multiple...
In this investigation, the monostatic inverse synthetic aperture radar (ISAR) characteristics of electrically large zigzag-grooved structures were numerically analyzed for the far-field at X-band frequencies. The zigzag-grooved structures were all assumed to have perfect electric conductor (PEC) properties. Their ISAR data were post-processed from their monostatic radar cross section (RCS) data generated...
In this work, microwave heating of a buried target by a non-planar Electromagnetic (EM) wave source is investigated numerically using the Finite-Difference Time-Domain (FDTD) technique. Such a non-planar wave source is obtained by placing the target in the Fresnel region of a circular aperture representing a parabolic reflector antenna. The Huygen's source equivalence procedure is used to model the...
The RCS of an obliquely truncated rectangular cavity is modeled by using AI and modal rays are validated by comparison with the PTD based RAPPORT code. Very good agreement was obtained.
