Due to their anomalous features they have attracted signifi cant atten-tion and research interest the past decade. Their fascinating properties do stem from average composition, as for conventional mixtures, but are instead based on specifi c arrangement geometry of structural elements which composed. popularity is associated with pos-sibility tune operation frequency functionality by tai-loring these constituent meta-atoms, providing functionalities such negative refraction,
