A virtual element approximation for the modified transmission eigenvalues for natural materials
Liangkun Xu, Shixi Wang, Hai Bi
In this paper, we discuss a virtual element approximation for the modified transmission eigenvalue problem in inverse scattering for natural materials. In this case, due to the pos…
