Abstract:

A two-dimensional discrete complex image method (DCIM) is used to calculate the Green functions in the layered medium when field point and source point are located in different layers. Firstly the spectral kernel function is expressed as two-dimension exponential series by two-dimensional estimation of signal parameters via rotational invariant techniques (ESPRIT), then Sommerfeld identity is used to get the closed form Green functions in spatial domain. The numerical interpolation is avoided and numerical simulation results confirm the correctness of this method.
