Broadband mode conversion via gradient index metamaterials

We propose a design for broadband waveguide mode conversion based on gradient index metamaterials (GIMs). Numerical simulations demonstrate that the zeroth order of transverse magnetic mode or the first order of transverse electric mode (TM(0)/TE(1)) can be converted into the first order of transver...

Descripción
Sumario:We propose a design for broadband waveguide mode conversion based on gradient index metamaterials (GIMs). Numerical simulations demonstrate that the zeroth order of transverse magnetic mode or the first order of transverse electric mode (TM(0)/TE(1)) can be converted into the first order of transverse magnetic mode or the second order of transverse electric mode (TM(1)/TE(2)) for a broadband of frequencies. As an application, an asymmetric propagation is achieved by integrating zero index metamaterials inside the GIM waveguide.
