摘　　要：利用在共面波导传输线上加载电容电感实现了单负材料,对由电单负材料和磁单负材料组成的异质结中电磁波的传播特性进行了研究。结果表明:由于电磁波能够在由两种单负材料组成的异质结中发生隧穿,利用基于共面波导传输线的单负材料异质结则可以实现具有亚波长特性的谐振腔,并且加载电容电感周期性的破坏对异质结中电磁波隧穿现象的发生及隧穿频率没有影响。The propagation properties of electromagnetic waves in heterostructure constructed by epsilon-negative and mu-negative materials were investigated experimentally,utilizing the single negative materials fabricated through loading lumped-element capacitors and inductors on coplanar waveguide（CPW）.The results show that the subwavelength cavity resonator can be realized by using the single negative materials heterostructure based on CPW,due to the tunneling properties of electromagnetic waves in heterostructure.Furthermore,the occurring of tunneling phenomenon and even the tunneling frequency is insensitive to the breakdown of periodicity of loading capacitors and inductors.
