S. Caorsi et M. Raffetto, ELECTROMAGNETIC BOUNDARY-VALUE PROBLEM IN THE PRESENCE OF A PARTLY LOSSY DIELECTRIC - CONSIDERATIONS ABOUT THE UNIQUENESS OF THE SOLUTION, IEEE transactions on microwave theory and techniques, 44(8), 1996, pp. 1511-1513
This paper deals with the uniqueness of the solution of a boundary val
ue problem defined by specifying the tangential components of the elec
tric field over the closed regular boundary (or the tangential compone
nts of the magnetic field over the boundary, or the former components
over part of the boundary and the latter components over the rest of t
he boundary) of a limited region containing a linear dielectric materi
al not lossy everywhere. In particular, the uniqueness of the solution
is proved in the case where the dielectric is everywhere linear, homo
geneous, and lossless, except for a subregion where the dielectric is
lossy, linear but not necessarily homogeneous.
