| Abstract: | By using the coordinate transformation method, we have deduced the
material parameter equation for rotating elliptical spherical cloaks
and carried out simulation as well. The results indicate that the
rotating elliptical spherical cloaking shell, which is made of
meta-materials whose permittivity and permeability are governed by
the equation deduced in this paper, can achieve perfect invisibility
by excluding electromagnetic fields from the internal region without
disturbing any external field. |
