An Efficient Sampling Method for the Interpolation/Extrapolation of Electromagnetic Responses in Time and Frequency Domain

The higher order maximal orthogonal vector basis functions are used to get target's sampling information in interpolation/extrapolation of electromagnetic responses in time and frequency domain. With the method, the computational complexity of sampling would decrease sharply without loss of accuracy. As a result, the proposed method solved the problem of high computational complexity and great resource consuming of traditional sampling method. Some numerical results are given to verify the high efficiency and accuracy of this method.
