Analysis of layered media terminated with an impedance surface varying in lateral directions
İdemen, Mehmet Mithat; Alkumru, Ali (Springer-Verlag Berlin, 2000)Determination of the constitutive parameters of a region from data provided by remote sensing is an extremely interesting and important topic from various points of view. In a large class of problems of this type, the ... -
Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
İdemen, Mehmet Mithat; Alkumru, Ali (Elsevier Science BV, 2005-06)During the second half of the last century mixed boundary-value problems had been an appealing research subject for both mathematicians and engineers. Among this kind of problems those connected with wave propagation in ... -
Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
İdemen, Mehmet Mithat; Alkumru, Ali (2004)Among the wave propagation problems, those connected with half-spaces bounded by sectionally homogeneous boundaries take important place because they are motivated by microwave applications. If the boundary are of three ... -
A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries
İdemen, Mehmet Mithat; Alkumru, Ali (Oxford Univ Press, 2000-08)The classical Wiener-Hopf method connected with mixed two-part boundary-value problems is generalized to cover n-part boundaries. To this end one starts from an ad-hoc representation for the Green function, which involves ... -
Influence of the velocity on the energy patterns of moving scatterers
İdemen, Mehmet Mithat; Alkumru, Ali (Taylor & Francis, 2004)Parallel to the developments in the communication through space vehicles achieved during the last two decades, the scattering problems connected with moving objects became more and more important from both theoretical and ... -
A new method for the source localization in sectionally homogeneous bounded domains involving finitely many inner interfaces of arbitrary shapes
İdemen, Mehmet Mithat; Alkumru, Ali (Pergamon-Elsevier Science, 2001-05)A new method to localize a static point source buried in a nonhomogeneous bounded domain composed of finitely many homogeneous parts separated by interfaces of arbitrary shapes was established. The source can be a simple ... -
On a class of functional equations of the Wiener-Hopf type and their applications in n-part scattering problems
İdemen, Mehmet Mithat; Alkumru, Ali (Oxford Univ Press, 2003-12)An asymptotic theory for the functional equation K-phi=f, where K : X-->Y stands for a matrix-valued linear operator of the form K=K1P1+K2P2+...+KnPn, is developed. Here X and Y refer to certain Hilbert spaces, {P-alpha} ...
