A comparative study of RCS predictions of canonical rectangular and circular cavities with double-layer material coating
(Denshi Jouhou Tsuushin Gakkai,Institute of Electronics Information and Communication Engineers, 1997-11)A rigorous radar cross section (RCS) analysis is carried out for two-dimensional rectangular and circular cavities with double-layer material loading by means of the Wiener-Hopf (WH) technique and the Riemann-Hilbert problem ... -
Design and analysis of slotted sectoral waveguide array antennas embedded in cylindrically stratified media
(IEEE, 2014-07)Slotted waveguide antennas are being widely used in military and commercial applications for many decades. Low cross-polarization, 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
(IEEE, 2014)We present an algebraic compression technique to accelerate the computation of multiple monostatic radar cross sections of arbitrary 3-D geometries. The method uses adaptive cross approximation, followed by a recompression ... -
Investigation of metamaterial coated conducting cylinders for achieving transparency and maximizing radar cross section
(IEEE, 2007)Recently, reducing the radar cross sections (RCS) of various structures to achieve transparency and obtaining resonant structures aimed at increasing the electromagnetic intensities, stored or radiated power levels have ... -
Large flat plate models in the physical optics method for RCS calculations
(IEEE, 2004-09)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 cross-section using the interplay of go-like ray effects and resonances
(Institute of Electrical and Electronics Engineers, 2015)A triangular dielectric cylinder (dielectric prism) of the size, in cross-section, comparable to or moderately larger than the wavelength is a scatterer, which blends together two different types of electromagnetic behavior: ... -
Radar cross-section study of cylindrical cavity-backed apertures with outer or inner material coating: the case of E-polarization
(IEEE, 1993)A dual-series-based solution is obtained for the scattering of an E-polarized plane wave from a cavity-backed aperture which is formed by a slitted infinite circular cylinder coated with absorbing material. The material ... -
Radar cross-section study of cylindrical cavity-backed apertures with outer or inner material coating: the case of H-polarization
(Institute of Electrical and Electronics Engineers, 1995-05)A dual-series-based solution is obtained for the scattering of an H-polarized 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 cavity-backed apertures with outer or inner material coating: the case of e-polarization
(IEEE, 1993)Cavity-backed 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
(Wiley-Blackwell Publishing, Inc., 2003)Bistatic radar cross section (BRCS) values of a stealth airborne target are predicted by performing both scaled-model measurements and numerical simulations. In order to achieve the solution of large-scale electromagnetic ... -
Wave propagation in metamaterial structures and retrieval of homogenization parameters
(Bilkent University, 2007)Electromagnetic wave propagation in metamaterial structures (metamaterial slabs, metamaterial cylinders, metamaterial coated conducting cylinders etc.) are investigated. Scattered and transmitted electromagnetic fields ...
