Electromagnetic scattering from multiple rectangular apertures in a thick conducting screen

open access: yesIEEE Transactions on Antennas and Propagation, 1999
Electromagnetic wave scattering from multiple rectangular apertures in a thick conducting screen is studied. The Fourier-transform and mode-matching technique are used to obtain simultaneous equations for the modal coefficients. The simultaneous equations are solved to represent the scattered and transmitted fields in series forms which are suitable ...

Acoustic scattering from a rectangular aperture in a thick hard screen

open access: yesThe Journal of the Acoustical Society of America, 1997
Acoustic scattering from a rectangular aperture in a thick hard screen is examined. The Fourier transform is used to represent the scattered wave in the spectral domain and the boundary conditions are enforced to represent a solution in closed form.

Calculation of near field of dipole placed above rectangular screen

2015 International Conference on Antenna Theory and Techniques (ICATT), 2015
A new technique for calculation of a diffracted field excited by a half-wave dipole on the edges of a finite size rectangular screen, at any observation point of a near zone is described. The technique is based on the laws of the geometric theory of diffraction with using the uniform diffraction factors obtained from the exact solution of a diffraction

Optimization of Directive Gain of Two Impedance Monopoles Located on Metal Rectangular Screen

IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021
On the base of the solving of the 3-D vector problem of diffraction of the fields of two impedance monopoles located on a perfectly conducting rectangular screen the fast active software for calculating directive gain in the maximum radiation D max of two impedance monopoles are developed.
