In this paper, a fast and accurate method for extracting surface and leaky wave poles in planar multilayered structure is reported, which is based on GPU/CPU heterogeneous platform. To realize high-level parallel computing, the way to balance hardware computing and communications between different units are discussed in detail. By accurately extracting all the discrete poles on the complex plane,...
A novel kind of Buffa-Christiansen (BC) functions is developed for improving the surface combined field integral equation with impedance boundary condition (CFIE-IBC) from three-dimensional imperfectly conducting objects. With difference from the original BC function in wide use, the novel BC function is dimensionless as the RWG function, which makes the and components of the resulting matrix...
In this paper, based on the frequency-varied relationship between surface wave poles and leaky wave poles of spectral Green's functions for a layered medium, a new method for fast locating the leaky wave poles at the given operating frequency is established. This method locates the leaky wave poles at the given operating frequency by consecutive frequency perturbations with the surface wave poles...
