Research output: Contribution to conferencePosterpeer-review


It is shown how spectra of any harmonic order may be obtained from time-domain simulation of devices involving sinusoidal modulation of the constituent materials. The technique<br>involves conducting multiple simulations in which the global<br>phase of the modulating signals is progressively incremented. The 0.4 ensuing simulation results are linearly combined to extract the 0.2 harmonic order of interest. The technique is demonstrated via finite-different time-domain analysis of a space-time modulated<br>surface which shows good agreement with theoretical calculations.<br>
