A Generalized Dispersion Equation Combining Coupled Modes, Parity-Time Symmetry, and Leaky Waves Describing Non-Decaying Leaky Surface Waves

Afshin Abbaszadeh, Jordan Budhu

A generalized dispersion equation is derived featuring coupled mode theory, parity-time symmetry, and leaky wave antennas of arbitrary periodic modulation. It can be specialized to…
