“…Some antennas for radar systems are designed to receive and transmit signal on the same polarization (e.g., HH for horizontal receive and horizontal transmit and VV for vertical receive and vertical transmit), while some complex radar system antennas may be designed transmitting and receiving components working on different polarizations (e.g., HV for horizontal transmit and vertical receive and VH for vertical transmit and horizontal receive). Antennas for radar systems can present various levels of polarization combination, e.g., single-level polarization (HH, VV, VH, or HV), double-level polarization (HH, VV; HH, HV; or VV, VH), triple-level polarization (HH, VV, HV or HH, VV, VH), and fourfold-level polarization (HH, VV, VH, HV) [18][19][20][21][22][23][24][25][26][27].…”

The manuscript reviews the current literature on scattering applications of RADAR (Radio Detecting And Ranging) in remote sensing and diagnostics. This paper gives prime features for a variety of RADAR applications ranging from forest and climate monitoring to weather forecast, sea status, planetary information, and mapping of natural disasters such as the ones caused by earthquakes. Both the fundamental parameters involved in scattering mechanisms of RADAR applications and the factors affecting RADAR performances are also discussed.

“…Thus far, the KP method is applied to specific geometries including flanged waveguides, rectangular strips and cracks, rectangular slits, and rectangular and circular plates and holes [6][7][8][9][10][11][12][13][14][15][16]. In many related works, the geometry of the structure has remained the same and only the medium is changed [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. In addition, the representation of the method and its numerical implementation is complicated and requires some knowledge about hypergeometric functions and Jacobi's polynomials.…”

<p>Application of the method of Kobayashi potentials (KP) is extended to the electromagnetic (EM) diffraction from the parallel-plate T-junction. Standard integral identities are used for problem formulation, without direct usage of Weber-Schafheitlin (WS) integrals. The Fourier function space is exploited for the construction of the governing linear equations. A simple strategy is suggested for the evaluation of the required improper integrals. Numerical results are validated through convergence analysis.</p>

An analysis of multiple scattering by two Perfect Electric Conducting (PEC) spheres using translation Addition Theorem (AT) for spherical vector wave functions is presented. Specifically, the Cruzan formalism is used to represent the AT for spherical harmonics, which introduces the translation coefficients for transformation of spherical harmonics from one coordinate to another. The adoption of these coefficients with the use of two PEC spheres in a near zone region makes the calculation of multiple scattering electric fields very efficient. As an illustration, the mathematical formation using advanced computational approaches was inspected. Then, the generic truncation criteria in the scattered electric field by two PEC spheres was deeply investigated using translation AT. However, the numerical validation was obtained using Comsol simulation software. This approach will allow to evaluate the scattering from macro-structures composed of spherical particles, i.e., biological molecules, clouds of airborne particles, etc. An original and fully general solution to the problem using vector quantities is introduced, and the convergence of the solution in several numerical examples is also demonstrated. This approach takes into account the effect of multiple scattering by two PEC spheres for spherical vector function.
