Abstract

Time reversal (TR) is a technique used to focus electromagnetic energy at a precise location by injecting timereversed signals recorded from an initial pulse. In conventional cavities, TR is constrained by the diffraction limit, reducing the efficiency of refocalization and requiring intrusive measurements. This paper proposes using spoof surface plasmon polaritons (SSPPs) on a corrugated surface instead of electromagnetic waves in a homogeneous volume. Simulations demonstrate that SSPPs reduce the focal spot size and limit the need for intrusive measurements. The results highlight the potential of SSPPs for precise energy delivery in electromagnetic systems, with applications such as plasma ignition.
