Propagation simulation for outdoor wireless communications in urban areas
(Bilkent University, 2002)A propagation simulation of wireless communication for urban environments is aimed. Firstly, propagation path loss from a base station to a receiver point was calculated according to Walfisch-Ikegami model which is an ... -
Radar cross section (RCS) of perfectly conducting (PEC) thin wires and its application to radar countermeasure: Chaff
(Bilkent University, 2015)In electronic warfare, active and passive countermeasures are used to jam threat RF radars. While electronic jamming pods are accepted as an active one, chaff is accepted as a passive countermeasure that consists of ... -
Radiation fields of a complex source in 2-D circular radome with metal gratings
(Bilkent University, 1997)In this thesis, the transmission effect of a two-dimensional circular radome with periodic metal gratings is analyzed. We started with the study of gratings consisting of periodic arrays of thin lossy strips surrounded ... -
Radiation fields of the line source in a cylindrical wire grating
(Bilkent University, 1998)In this thesis, the transmission effect of a grid structure is analyzed. The grid structure is intended to model the metallic support elements of a radome. The total field for the real and complex position line sources ... -
RCS computations with PO/PTD for conducting and impedance objects modeled as large flat plates
(Bilkent University, 2005)Calculation of Radar Cross Section (RCS) of arbitrary bodies using Physical Optics (PO) Theory and Physical Theory of Diffraction (PTD)is considered. For bodies with impedance surface boundary condition, only PO is used. ... -
Scattering from impedance objects at the edge of a perfectly conducting wedge
(Bilkent University, 2012)In this study, scattering from impedance bodies positioned at the edge of a perfectly conducting (PEC) wedge is investigated. In the treatment of the problem, eigenfunction expansion in terms of spherical vector wave ... -
A study of line source fields transmitted through a 2D circular dielectric radome or a slab
(Bilkent University, 1996)In this thesis, far field solutions for the real and complex line sources surrounded by a cylindrical dielectric shell (radonie) are obtained in both E and H polarizations. These far fields for the radoine model are then ...
