Summary:
The conventional Lagrange interpolation scheme, which has demonstrated a very high efficiency in approximating the quasi-static Greens’ functions, is not very effective for interpolating full-wave Green’s functions due to their highly oscillatory characteristics of the phase term. To alleviate this difficulty, we propose a new full-wave interpolation scheme in which a well-designed phase compensation technique is employed. Applying this technique in 2-D non-uniform Lagrange interpolations, we can approximate the Green’s functions in an area of 100 x 100 λ2 with an accuracy of 10-3, using only 90 x 90 Chebyshev interpolation points. The proposed scheme can be adopted to build a fast solver for full-wave electromagnetic simulations.
