#### A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries

(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 ...

#### On a class of functional equations of the Wiener-Hopf type and their applications in n-part scattering problems

(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} ...

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

(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 ...

#### Influence of the velocity on the energy patterns of moving scatterers

(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

(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 ...

#### Scattering of electromagnetic waves by a rectangular impedance cylinder

(Elsevier Science, 2000-04)

A uniformly valid asymptotic solution is developed for the diffraction of a high-frequency wave by an infinitely long rectangular cylinder having different impedance walls. The incident wave is generated by a line source ...

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

(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 ...

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

(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 ...

#### Derivation of the Lorentz transformation from the Maxwell equations

(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 ...
