Research to Apply Metamaterial to Microwave Devices by Pseudo Multiscale FDTD Method

在本研究中，将电磁场分析技术与等效电路计算相结合，改进了LE-FDTD方法，用于分析具有自然界中所不存在的性质的超材料。该方法对于超材料的实际应用和利用超材料制作微波器件具有重要意义，并成功地应用于超材料器件的分析。此外，我报告说，与有限元方法相比，只需要大约1/10的时间和内存。

In this research, the LE-FDTD method that is the electromagnetic field analysis technique integrated to the equivalent circuit calculation is enhanced to analyze the metamaterial with the property that does not exist in the nature. This method is very important for facilitating applications using the metamaterial, and for proposing microwave devices by using them.As a result, I succeeded in analyzing the metamaterial device by this proposing technique. Furthermore, I reported that only time and the memory of about 1/10 are needed compared with the finite element method.
