| Abstract | ||
| This paper introduces different varieties of novel composite right / left handed metamaterials devices with novel magnetic operation properties. The reported devices are discussed in terms of their theoretical. The reported devices have the advantages of their small size, multi frequency band in addition to broadband operation (≈60 %) compared to their conventional design. Moreover, these devices are designed to illustrate novel magnetic properties such as their tuning and non reciprocity operation capabilities. Theoretical explanations supported by simulation results of presented devices confirmed the operation of a tunable and nonreciprocal coupler and tunable transformer. The novelty and advantage of the reported devices are their combined properties of compactness and nonreciprocity. Furthermore the devices require very low external DC magnetic bias due to its much lower demagnetization compared to the microstrip configuration. Accordingly, the devices can be applied in many RF front end novel applications such as circulators and isolators. | ||
