WebBecause of the standing wave component we can not define wave fronts, as we did with the plane and cylindrical spectra. One could expand the Legendre functions into traveling wave components using cos θ = ( eiθ + e-iθ) / 2 to develop expressions purely in terms of traveling waves ( eimϕ+inθ ). WebIt takes advantage of cylindrical wave expansion functions and matches the boundary conditions at both the metal-to-insulator and insulator-to-silicon interfaces exactly. The method is validated against a full-wave finite-element method solver, and analysis examples using the method are demonstrated in a frequency range up to 100 GHz.
