This paper describes the use of a two-dimensional (2D) method of moments analysis for electromagnetic scattering & radiation from objects comprised of both conducting and penetrable material (that is, composite objects). Such analyses are not available as existing commercial codes. Yet two-dimensional analyses are often able to reveal information about a situation whose 3D analysis is not feasible...
To reflect the accurate characteristics of targets, plane wave should be assumed around the target. However, the plane wave does not always keep its infinite width in the far field. As a result, we assume incident beam wave with limited width. In this paper, laser radar cross-section (LRCS) is calculated. This task is necessary particularly when LRCS calculation is for targets with inflection points...
With rapidly increasing demand for bandwidth, and the recent advances in nano-metric Si-based integrated circuit technologies, millimeter-wave (mmW) systems are finding numerous commercial applications, which, unlike military and scientific usages, are extremely cost sensitive. A wide range of applications at mmW frequencies can be found in such area as wireless communications network (60 GHz), automotive...
In this paper, the performances of the neural-network approach for discrimination of the landmine depth from the ground surface and the landmine radius are carried out. A sensor for landmines detection consists of two microstrip antennas is used. One of the antennas is used as transmitting antenna and the second is considered as receiving antenna. Circular cylindrical shape metallic landmine is used...
This paper presents analysis of the electromagnetic scattering from the grounded dielectric slab loaded with periodic conducting strip grating using modal expansions. It is shown that this structure can act as an either artificial magnetic conductor (AMC) or artificial electric conductor (AEC) depending on the polarization of the incident wave. This study encompasses the dependence of AMC or AEC characteristics...
