The newly discovery of lefthanded material has been regarded as one of the ten most significant discoveries by science in 2020. The successful realization of metamaterials has garnered considerable attentions and discussions all over the world, and has been the front and focus area in physics and electromagic research. In this paper, some electromagic characteristics of metamaterials and application in microwave circuit are studied thoroughly. The main contents are listed as follows: (1) The present research status on metamaterials around the world and analysis of the theoretical and experimental basis of metamaterials are introduced. Comparing with the traditional material,detail description about the wave reflection and transmission in some equivalent isotropy metamaterial models are made. (2) The structure characteristics and applications of The Rod Array、 Split Ring Resonator(SRR)、 Complementary Split Ring Resonator(CSRR) and Composited Right/Left Handed (CRLH) are studied. At the same time, the reason of why those Structures have negative permittivity or negative permeability. (3) The application of metamaterials in microwave filters and antennas are studied. Metamaterials have been used to design to microwave filters and antennas, and using the high frequency simulation software calculates the optimize results. The performance of microwave devices have been increased significantly. Key words: Metamaterials。 Metamaterial Antenna. 目 錄 1 緒論 .................................................................................................................. 1 引言 ............................................................................................................. 1 課題在國內(nèi)外的研究概況 .......................................................................... 1 異性介質(zhì)的研究概況 ......................................................................... 1 微波器件研究概況 ............................................................................. 2 高頻仿真軟件 ANSOFT HFSS 的介紹 ..................................................... 2 Ansoft HFSS 簡介 ............................................................................... 2 建立 HFSS 工程的一般過程 ............................................................... 3 本文研究內(nèi)容 ............................................................................................. 3 對異向介質(zhì)特性進行了研究 ............................................................. 3 對異性介質(zhì)天線和濾波器進行了研究 ............................................. 3 論文的結(jié)構(gòu)安排 ......................................................................................... 3 2 異向介質(zhì)基本特性 ............................................................................................ 5 異向介質(zhì)的產(chǎn)生與發(fā)展 ............................................................................. 5 異向介質(zhì)特性的理論研究 ......................................................................... 6 左手螺旋特性 ..................................................................................... 6 負折射現(xiàn)象 ......................................................................................... 7 逆向多普勒效應 ................................................................................. 7 周期細金屬棒陣列的應用 ................................................................. 8 分裂諧振環(huán)和互補分裂諧振環(huán)的應用 ............................................. 9 復合左 /右手傳輸線的應用 ............................................................. 10 3 異向介質(zhì)天線 .................................................................................................. 12 天線基礎(chǔ)與定義 ....................................................................................... 12 天線綜述 ........................................................................................... 12 天線的基本性能參數(shù) ....................................................................... 12 微波天線的設計原理 ............................................................................... 14 天線的輻射機理 ............................................................................... 14 天線的場區(qū)和方向圖 ....................................................................... 16 異向介質(zhì)天線的設計與仿真分析 ........................................................... 18 4 異向介質(zhì)濾波器 .............................................................................................. 25 微波濾波器的基本理論 ........................................................................... 25 微波濾波器綜述 ............................................................................... 25 微波濾波器的基本性能參數(shù) ........................................................... 26 微波濾波器的設計原理 ........................................................................... 27 濾波 器電路的微波實現(xiàn) ................................................................... 27 微波低通濾波器 ............................................................................... 29 微帶帶通濾波器 ............................................................................... 31 異向介質(zhì)濾波器的設計與仿真分析 ....................................................... 34 5 總結(jié)與展望 ...................................................................................................... 39 總結(jié) ........................................................................................................... 39 展望 ........................................................................................................... 39 參考文獻 .............................................................................................................. 40 英文原文 .....
