有限差分表达式 finite-difference expression
- 接下将复化光晶微带天线以有限时域差分表达式进行电磁波模拟,而本文于有限时域差分表达式之模拟多考虑两介质交接面之处理,因复化光晶微带天线与一般微带天线之差别除了结构模型变小且更复杂外、对于两介质交接面亦会增加对系统之影响,本文依此论证此影响外并也因考虑了此因素而提高有限时域差分表达式模拟之准确度。
In addition to that, this paper also consider the influence between two material interfaces, since complicated photonic crystal micro-strip antenna is different from that of the traditional micro-strip antenna, not only minimization, but to complicated in shape, It also get better effect on enhancing two material interfaces.
