Time-reversal approaches provide a simple design optimization procedure for a class of electromagnetic components. The approach comprises iterations of forward and reverse time simulations that can be undertaken using any numerical time-domain algorithm. However, although this offers significant flexibility, it is computationally intensive, and therefore, it is important to increase the convergence...
Time‐reversal simulations using conventional numerical algorithms provide the basis for a simple component optimization procedure. However, the computational requirements of the approach can become excessive, requiring the recording of the complete field time histories on a surface surrounding the problem space. In this work temporal, spatial and modal filtering methods are employed to significantly...
