Perfect conversion of a TM surface-wave into a TM leaky-wave by an isotropic periodic metasurface printed on a grounded dielectric slab
Svetlana Tcvetkova, Enrica Martini, Sergei Tretyakov +1
This paper presents an exact solution for a perfect conversion of a TM-polarized surface wave (SW) into a TM-polarized leaky-wave (LW) using a reciprocal and lossless penetrable me…
Exact Solution for the Protected TEM edge mode in a PTD-Symmetric Parallel-Plate Waveguide
Enrica Martini, Mario G. Silveirinha, Stefano Maci
A Parity Time-reversal Dual (PTD) symmetric structure constituted by a Perfectly-Electric-Perfectly magnetic (PEC-PMC) parallel plate waveguide (PPW) is analyzed. This waveguide su…
Exact solution for surface wave to space wave conversion by periodical impenetrable metasurfaces
Svetlana N. Tcvetkova, Stefano Maci, Sergei A. Tretyakov
We show that there exists an exact solution for a lossless and reciprocal periodic surface impedance which ensures full conversion of a single-mode surface wave propagating along t…
Alternative Derivation of Electromagnetic Cloaks and Concentrators
Arthur D. Yaghjian, Stefano Maci
Beginning with a straightforward formulation of electromagnetic cloaking that reduces to a boundary value problem involving a single Maxwell first-order differential equation, expl…
