Complex analytic dependence on the dielectric permittivity in ENZ materials: The photonic doping example
Abstract Motivated by the physics literature on āphotonic dopingā of scatterers made from āepsilonānearāzeroā (ENZ) materials, we consider how the scattering of timeāharmonic TM electromagnetic waves by a cylindrical ENZ region is affected by the presence of a ādopantā in which the dielectric permittivity is not near zero. Mathematically, this ā¦
