Operator form of the generalized optical theorem for wave problems
نویسندگان
چکیده
The operator form of the generalized optical theorem (OT) obtained earlier for scalar wave equation is extended to case electromagnetic radiation, as well other equations. It shown that in transition from usual OT, instead "forward" scattering amplitude, diagonal matrix element T-scattering corresponding incident appears. transitions known forms OT following special cases are also illustrated. Keywords: energy conservation, theorem, observations near and far zones, radiation losses.

15 صفحه اولGENERALIZED PRINCIPAL IDEAL THEOREM FOR MODULES
The Generalized Principal Ideal Theorem is one of the cornerstones of dimension theory for Noetherian rings. For an R-module M, we identify certain submodules of M that play a role analogous to that of prime ideals in the ring R. Using this definition, we extend the Generalized Principal Ideal Theorem to modules.
متن کاملA Generalized Form of Tellegen’s Theorem
Absfract-Among the theorems of circuit theory, Tellegen’s theorem is unusual in that it depends solely upon Kirchhoff’s laws and the topology of the network. The theorem therefore applies to all electrical networks that obey Kirchhoff’s laws, whether they be linear or nonlinear, time-invariant or time-variant, reciprocal or nonreciprocal, hysteretic or nonhysteretic; the excitation is arbitrary...
