Loss compensation symmetry of unequally sized dielectric cylinders with gain and loss
Anton V. Hlushchenko, Vitalii I. Shcherbinin, Denis V. Novitsky +1
A rigorous analytical approach is applied to solve the eigenvalue problem for a pair of circular dielectric cylinders with complex permittivity. This approach relies on field expan…
