A comparative study of RCS predictions of canonical rectangular and circular cavities with doublelayer material coating
(Denshi Jouhou Tsuushin Gakkai,Institute of Electronics Information and Communication Engineers, 199711)A rigorous radar cross section (RCS) analysis is carried out for twodimensional rectangular and circular cavities with doublelayer material loading by means of the WienerHopf (WH) technique and the RiemannHilbert problem ... 
Design and analysis of slotted sectoral waveguide array antennas embedded in cylindrically stratified media
(Institute of Electrical and Electronics Engineers Inc., 2014)Slotted waveguide antennas are being widely used in military and commercial applications for many decades. Low crosspolarization, high power capacity, ease of fabrication in microwave bands, and the ability to form arrays ... 
The examination of new equivalent edge currents in the prediction of high frequency backscattering from flat plates
(Bilkent University, 1991)Equivalent edge currents based on the geometrical theory of dilfraction (GTD) have been utilized for the prediction of electromagnetic scattering from edged bodies. These equivalent currents are use Keller’s diffraction ... 
Fast solution of electromagnetic scattering problems with multiple excitations using the recompressed adaptive cross approximation
(Institute of Electrical and Electronics Engineers Inc., 2014)We present an algebraic compression technique to accelerate the computation of multiple monostatic radar cross sections of arbitrary 3D geometries. The method uses adaptive cross approximation, followed by a recompression ... 
Integralequation study of ray effects and naturalmode resonances in a 2D dielectric prism
(Institute of Electrical and Electronics Engineers Inc., 2015)We analyze the interplay of two different types of electromagnetic behavior demonstrated by a 2D dielectric prism: Geometrical Optics and resonance. As it is shown, the first is responsible, for instance, for enhanced ... 
Large flat plate models in the physical optics method for RCS calculations
(2004)The calculation of Radar Cross Section (RCS) of arbitrarily large perfectly conducting body is presented. The body is modelled as triangular meshes of any size by the help of graphical tools. For the calculation of scattered ... 
Manipulation of backscattering from a dielectric cylinder of triangular crosssection using the interplay of golike ray effects and resonances
(Institute of Electrical and Electronics Engineers, 2015)A triangular dielectric cylinder (dielectric prism) of the size, in crosssection, comparable to or moderately larger than the wavelength is a scatterer, which blends together two different types of electromagnetic behavior: ... 
POMLFMA hybrid technique for the solution of electromagnetic scattering problems involving complex targets
(2007)The multilevel fast multipole algorithm (MLFMA) is a powerful tool for efficient and accurate solutions of electromagnetic scattering problems involving large and complicated structures. On the other hand, it is still ...

(Institute of Electrical and Electronics Engineers, 199505)A dualseriesbased solution is obtained for the scattering of an Hpolarized plane wave from a slitted infinite circular cylinder coated with absorbing material from inside or outside. For both cases, numerical results ... 
RCS study of cylindrical cavitybacked apertures with outer or inner material coating: the case of Epolarization
(IEEE, 1993)Cavitybacked apertures (CBA) are encountered as parts of any airborne or spaceborne radar targets. Most familiar of them are, probably, air inlets and engine tubes, known to contribute a great deal to radar cross section ... 
Validation through comparison: measurement and calculation of the bistatic radar cross section of a stealth target
(WileyBlackwell Publishing, Inc., 2003)Bistatic radar cross section (BRCS) values of a stealth airborne target are predicted by performing both scaledmodel measurements and numerical simulations. In order to achieve the solution of largescale electromagnetic ...
