Propagation Sweeps

Propagation Sweeps#

Sweeps reuse previously computed EME mode data, so bent cells remain subject to the same mode-consistency checks as the base simulation. In particular, bent anisotropic media with bend_medium_frame="global" are rejected when repetition or length changes would make a reused mode see a different local tensor orientation, and bent custom media are only supported when no global-frame remapping of custom data is required. If you instead resolve global-frame anisotropic bends with multiple cells, check convergence with respect to the number of EME cells.

Warning

EMEFreqSweep is deprecated. For new simulations, list the desired frequencies in EMESimulation freqs and control the performance/accuracy tradeoff with EMEModeSpec interp_spec.
