Numerical electromagnetic investigation of patterns of the external problem for the Huygens element that is the external Huygens cube

摘要

Patterns of the external Huygens cube with the edge that is much less than a wavelength, a half of a wavelength, and a wavelength are given. The dependence of its pattern shape on the boundary condition on the second input is shown. The paradox of the external Huygens cube is noted. The influence of the boundary condition on the unexcited input on its pattern is considered.
