Multi-layered Lossy Finite Length Dielectric Cylindirical Model of Man at Oblique Incidence
نویسندگان
چکیده
This paper is intended to give a simple electromagnetic formulation of the EM power absorption properties of multi – layered cylindrical model of man at RF frequencies and above. The formulation, however, has no limitations concerning frequency. Thus very low frequencies are also considered for comparison with the results in literature. Both horizontal and vertical polarizations are considered. A single general expression for model of man has been derived. Absorbed power density of man against different values of incident power are illustrated at different frequencies and compared with ICNIRP standards.

کاربرد روش معادله سهموی در تحلیل مسائل انتشار امواج داخل ساختمان
With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...
متن کاملRefraction at the Interface of a Lossy Metamaterial
The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...
متن کاملBessel beam through a dielectric slab at oblique incidence: the case of total reflection
The oblique incidence of a Bessel beam on a dielectric slab with refractive index n1 surrounded by a medium of a refractive index n > n1 may be studied simply by expanding the Bessel beam into a set of plane waves forming the same angle θ0 with the axis of the beam. In the present paper we examine a Bessel beam that impinges at oblique incidence onto a layer in such a way that each plane-wave c...
متن کاملWide-Band Electromagnetic Scattering from a Dielectric BOR Buried in a Layered Lossy Dispersive Medium
A method of moments (MoM) analysis is developed for electromagnetic scattering from a dielectric body of revolution (BOR) embedded in a layered medium (the half-space problem constituting a special case). The layered-medium parameters can be lossy and dispersive, of interest for simulating soil. To make such an analysis tractable for the wide-band (short-pulse) applications of interest here, we...
متن کاملFDTD Analysis of Top-Hat Monopole Antennas Loaded with Radially Layered Dielectric
Top-hat monopole antennas loaded with radially layered dielectric are analyzed using the finite-difference time-domain (FDTD) method. Unlike the mode-matching method (MMM) (which was previously used for analyzing these antennas) the FDTD method enables us to study such structures accurately and easily. Using this method, results can be obtained in a wide frequency band by performing only one ti...
