Article Citation - WoS: 18Citation - Scopus: 19Scattering by an Impedance Half-Plane: Comparison of the Solutions of Raman/Krishnan and Maliuzhinets/Senior(Electromagnetics Acad, 2009) Umul, Y. Z.There are three approaches for the solution of the diffraction problem of plane waves by an impedance half-plane in the literature. The diffracted field expressions, obtained by the related methods, are compared numerically. The examination of the scattered field shows that the most reliable solution is the field representation of Raman and Krishnan. Since the diffracted fields of Senior and Maliuzhinets do not compensate the discontinuities of the geometrical optics waves at the transition regions.Article Citation - WoS: 4Citation - Scopus: 4Electric Charges That Behave as Magnetic Monopoles(E M W Publishing, 2010) Umul, Y. Z.The memristor theory of Chua [1] provides a connection with the charge and magnetic flux in an electric circuit. We define a similar relation for the electric and magnetic flux densities in electromagnetism. Such an attempt puts forward interesting results. For example, the magnetic charges do not exist in nature however the electric charges behave as the magnetic monopoles in special media. We support our theory with the results of the recent experiments on materials named as spin ice.Article Citation - WoS: 2Citation - Scopus: 2The Physical Optics Integral of Creeping Waves(Taylor & Francis Ltd, 2012) Umul, Y. Z.The creeping waves, occurring in surface diffraction, are expressed as a physical optics surface integral. The scattering geometry and the implications of the surface integral are investigated in the context of the diffraction theory. The method is applied to the scattering problems of plane waves by an infinite parabolic conducting reflector. The results are analyzed numerically.
