并将H MRTD数值计算公式推广到了非均匀有耗媒质中.数值模拟结果同传统FDTD(Finite Difference Time Domain)方法及实验结果进行了比较.结果表明
每个波长只需取较少的空间离散网格
三维H MRTD时域全波分析方法便能较精确地模拟微机械微带天线
并能有效地减少CPU计算时间及节省计算机内存.

)is tunable in the range 1.7~2.3. The Haar-Wavelet-Based multiresolution time domain(H-MRTD)is used for modeling and analyzing the antenna for the first time. In addition
the mathematical formulae are extended to an inhomogenous media. Numerical simulation results are compared to those achieved using the conventional 3-D finite-difference time-domain(FDTD)method and measured. It has been demonstrated that
with this technique
space discretization with only a few cells per wavelength gives accurate results
leading to a reduction of both memory requirements and computation time.
