Upper bounds on scattering processes and metamaterial-inspired structures that reach them
(IEEE, 2014)
Artículo / Artikulua,
The physical limitations on time-harmonic scattering processes are investigated on the basis of the optical theorem. Previously derived least upper bounds on the total scattering and absorption cross-sections are obtained ...
Superbackscattering antenna arrays
(IEEE, 2015)
Artículo / Artikulua,
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering ...
Least upper bounds of the powers extracted and scattered by bi-anisotropic particles
(IEEE, 2014)
Artículo / Artikulua,
The least upper bounds of the powers extracted and
scattered by bi-anisotropic particles are investigated analytically.
A rigorous derivation for particles having invertible polarizability
tensors is presented, and the ...
