Abstract
Dyadic Green's function for a monolayer cylinder consisting of a cover with fully-populated surface conductivity tensor is formulated in this paper. Cylindrically wrapped densely packed graphene strips behaving as a hyperbolic meta-surface and arbitrary shaped graphene patterns supporting magneto-plasmons are investigated as two special cases. Closed-form approximate formulas based on effective medium theory (EMT) are available for the surface conductivity of the former and the latter can be analyzed by the effective tensor surface conductivity extraction by means of the finite element method (FEM). Both cases are treated under locally flat consideration of the conformal structures. Our formulation is based on the scattering superposition method by imposing the discontinuity boundary condition on tangential magnetic fields. Numerical examples are demonstrated to further validate the method for both guided and radiated modes.Entities:
