对Engheta双负介质谐振腔的研究

Research on Engheta Double Negative Media Cavity Resonators

针对"Engheta"所提出的一维双负谐振腔物模型进行进一步的理论探讨,分析了满足谐振方程的两组物理解,并就普通介质层和双负介质层界面发生反射时谐振腔的共振条件和稳定性进行分析,讨论普通介质层和双负介质层的阻抗不匹配时的一维亚波长谐振腔的稳定性问题.

Further discussion is given on the one-dimensional double negative resonator content model which is put forward by Engheta,and the two physical solutions to satisfy the resonance equation are analyzed;Meanwhile,the condition that ordinary medium layer and double negative medium layer interface produce reflection and its stability are analyzed,the stability question of one-dimensional sub-wavelength when the ordinary medium layer doesnot match with the double negative medium layers on impedance cavity resonator is discussed.
