Article Citation - WoS: 2Citation - Scopus: 2Diffraction of Electromagnetic Waves by a Resistive Half-Plane in Magneto-Ionic Plasma(Wiley-v C H verlag Gmbh, 2020) Umul, Yusuf ZiyaThe interaction of magnetic polarized electromagnetic wave with a resistive half-plane in magneto-ionic plasma is investigated. The method of transition boundary is used for the evaluation of the diffracted wave. The excitation of surface waves is examined in the medium and their diffracted fields are derived by using the diffraction theory for grazing incidence. The uniform field expressions are obtained with the aid of the uniform theory for evanescent waves. The behaviours of the derived scattered waves are studied numerically.Article Citation - WoS: 4Citation - Scopus: 4Transmission of a Bessel Beam Through a Circular Aperture in an Impedance Screen(Iop Publishing Ltd, 2014) Umul, Yusuf ZiyaThe scattering effect of a circular aperture, located in an impedance plane, on a Bessel beam is investigated by decomposing the scattered wave into two subcomponents, namely the geometrical optics and diffracted fields. The diffracted waves are investigated with the aid of the geometrical theory of diffraction. The detour parameter is evaluated and the existence zones of the geometrical optics fields are determined. The various aspects of the reflected and transmitted scattered waves, including the self healing of the beam, are studied numerically.
