| dc.description.abstract | 本論文的目的在於利用波動概念迭代處理法來分析一款頻率選擇表面。藉由不連續處橫向電磁場的連續方程式，該方法可得到連結頻率選擇表面之結構參數及其散射矩陣之關係式。據此，我們可以進行兩種分析設計。首先，從給定的結構參數可得到其散射矩陣；此外，更可合成出符合目標散射矩陣之結構參數組合。透過與HFSS模擬之結果比較，吾人分析並驗證了利用波動概念迭代處理法所得到的結果。 | zh_TW |
| dc.description.abstract | The objective of the present study is to analyse numerically a frequency selective surface using the Wave Concept Iterative Process Method (WCIP). By applying continuity equations between transverse electromagnetic fields at discontinuities, this method provide equations that link the structure's geometric and physics parameters to the S parameters. Consequently, two different reasoning can be conducted. First, an analysis, which consists in obtaining the S parameters, knowing the structure's geometric parameters. Second, a synthesis which consists in finding the optimum geometric parameters to fulfil specifications on the S parameters. The results obtained with the WCIP are analysed and validated by comparison with HFSS results. | en |
