A piecewise homogeneous spherical medium is excited by an external or internal electric
dipole with arbitrary location and polarization. The dyadic Green's function of the medium is …

This paper deals with the investigation of the direct and the inverse electromagnetic
scattering problem by a piecewise homogeneous sphere, excited by an interior or exterior …

A spherical electromagnetic wave is scattered by a bounded perfectly conducting obstacle.
A generalization of the plane‐wave optical theorem is established. For a spherical scatterer …

A layered sphere is excited by a time-harmonic spherical acoustic wave, generated by a
point source located either in the interior or in the exterior of the sphere. The sphere's core …

Acoustic excitation of a layered sphere by $ N $ external and internal point sources is
considered. The direct problem is solved by developing a T-Matrix method leading to the …

A detailed mathematical analysis of Stokes flow past a rigid biconcave disc shape, motivated
by the flow of blood plasma past a fixed red blood cell (RBC) is developed in the present …

A layered sphere is excited by an acoustic point source arbitrarily located inside or outside
the sphere. First, the direct scattering problem is solved analytically by developing a …

A spherical electromagnetic wave propagating in a chiral medium is scattered by a bounded
chiral obstacle which can have any of the usual properties. Reciprocity and general …

An acoustically soft or hard sphere which is covered by a penetrable concentric spherical
shell disturbs the propagation of an incident wave field emanating from a point source. The …

We consider the low‐frequency scattering problem of a point source generated incident field
by a small penetrable sphere. The sphere, which is also lossy, contains in its interior a co …
