Zero reflection and field enhancement by subwavelength nonconjugated single negative metamaterial pair

In this paper, zero reflection and field enhancement realized by subwavelength nonconjugated mu-negative and epsilon-negative metamaterial pair (NMEMP) are investigated. It is found although the impedance contrasts greatly at the interface, zero reflection can still be achieved by introducing subwavelength NMEMP. Moreover, the electromagnetic field distributions show that, only one component of the zero reflection mode (either electric or magnetic field) will be enhanced, with the other one suppressed simultaneously. Therefore, NMEMP is promising to be applied in modern optic and microwave communication systems for less reflection, flexible control of electromagnetic field and compact device volume.
