I once described a 240 GHz waveguide-structure radio receiver I had built as a “comprehensive analogue simulation of Maxwell’s equations incorporating realistic assumptions about the conductivity of real materials used in waveguide manufacture.” Although this simulation was insanely accurate, it was much more difficult to a) change parameters in this simulation and b) measure/calculate the results of this simulation than with the more traditional digital simulations of Maxwell’s equations we had available.
