Evert Klaseboer, Qiang Sun, Derek Y. C. Chan

AI总结:

本研究提出一种用于电磁脉冲时域散射的纯场积分方程方法,结合频域非奇异边界积分求解与傅里叶变换,实现宽波长范围稳定计算,可准确获取边界场信息并验证微光子学相关的局域场增强效应。

摘要:

本研究针对电磁脉冲散射问题,采用非奇异边界积分方法直接在频域求解场分量,再通过傅里叶变换得到完整的时空行为。该方法在波长相对于特征长度尺度较小或较大的情况下均保持稳定,可在材料边界上或边界附近准确获取场值的振幅与相位。研究还展示了微光子学应用中受关注的、由多重散射导致的局域场增强效应。

英文摘要:

The scattering of electromagnetic pulses is described using a non-singular boundary integral method to solve directly for the field components in the frequency domain, and Fourier transform is then used to obtain the complete space-time behavior. This approach is stable for wavelengths both small and large relative to characteristic length scales. Amplitudes and phases of field values can be obtained accurately on or near material boundaries. Local field enhancement effects due to multiple scattering of interest to applications in microphotonics are demonstrated.
