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 ...

Comments on "upper cutoff frequency of the bound wave and new leaky wave on the slotline"

İdemen, Mehmet Mithat; Büyükaksoy, İbrahim Alinur; Zehentner, Ján; Machac, J.; Migliozzi, M. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC., 1999-05)

For original paper see J. Zehentner et al., ibid., vol.46, pp.378-86 (Apr. 1998). In the above paper, Zehentner et al. claimed the identification of a new previously unidentified leaky wave on the slotline. They also believe ...

The concept of confluence and the edge conditions for a wedge bounded by material sheets

İdemen, Mehmet Mithat (IEEE, 2000)

The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges, in analytical studies they ...

Confluent edge conditions for the electromagnetic wave at the edge of a wedge bounded by material sheets

İdemen, Mehmet Mithat (Elsevier Science, 2000-07)

The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges. In analytical studies they ...

Confluent tip singularity of the electromagnetic field at the apex of a material cone

İdemen, Mehmet Mithat (Elsevier Science, 2003-09)

The tip singularity of the electromagnetic field at the apex of a cone (conical sheet) is investigated in its most general framework. To this end one considers, without loss of generality, a circularly symmetric cone which ...

Derivation of the Lorentz transformation from the Maxwell equations

İdemen, Mehmet Mithat (Vsp bv, 2005)

The Special Theory of Relativity had been established nearly one century ago to conciliate some seemingly contradictory concepts and experimental results such as the Ether, universal time, contraction of dimensions of ...

Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane

İdemen, Mehmet Mithat; Alkumru, Ali (Elsevier Science Bv, 2005-01)

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 ...

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 (Vsp Bv, 2004-01)

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 ...
