Scattering by a biisotropic obstacle and the properties of the Beltrami
spherical vector waves
- Gerhard Kristensson
Abstract
In this paper, we take a fresh look at the determination of the
transition matrix for a homogeneous, biisotropic particle employing the
Null-field approach. The condition for passivity of the material is
discussed. In particular, we focus on some previously unproved
properties of the Beltrami spherical vector waves, such as completeness,
orthogonality, and linear independence, which are all instrumental in
the analysis of the scattering problem with the Null-field approach.
Some numerical examples illustrate the approach.14 Oct 2023Submitted to Mathematical Methods in the Applied Sciences 15 Oct 2023Submission Checks Completed
