A great number of BPM algorithms, such as the FTBPM, various types of FDBPMs, wide angle approximations and adaptive FE-BPM are compared. The quasi-analytic character of the benchmark tests gains a deeper insight into the absolute accuracy.enfinite difference methodsintegrated opticsmodellingoptical waveguide theoryphysics computingsimulationbenchmark testsnumerical bpm algorithmscost project 240modelling workshopteupitzgermanybpm algorithmsftbpmfdbpmswide angle approximationsadaptive fe-bpmquasi-analytic characterabsolute accuracyintegrated optical circuit simulations621535journal article
