The source has a significant impact on the transient waveform produced by simulations. For exciting electromagnetic energy better, this letter presents a novel approach to impose a source in the implicit hybridizable Discontinuous Galerkin time-domain (imHDGTD) method. For the source terms (electric and magnetic currents), the implementation of imHDGTD is given in detail by adopting appropriate techniques. Compared with the explicit discontinuous Galerkin time-domain method, imHDGTD has a less number of degrees of freedom and the larger time step. Numerical results show its accuracy and efficient performance, which implies that the proposed method would be very useful for complex structures with different sources.

用于电磁学的隐式可混合不连续伽辽金时域方法中的一种新的施加源方法

源对仿真产生的瞬态波形有显着影响。为了更好地激发电磁能，这封信提出了一种在隐式可混合不连续伽辽金时域 (imHDGTD) 方法中强加源的新方法。对于源项（电流和磁流），通过采用适当的技术详细给出了 imHDGTD 的实现。与显式不连续伽辽金时域法相比，imHDGTD 的自由度数较少，时间步长较大。数值结果表明其准确性和高效性能，这意味着所提出的方法对于具有不同来源的复杂结构非常有用。
