Composite right/left‐handed (CRLH) metamaterial unit cell whose ground‐plane is defected with a rectangular dielectric slot is used to develop a single and multi‐pole pole bandpass filter. The unit cell comprises of serially connected interdigital capacitors whose junction is connected to a short‐circuited inductive stub. By defecting the ground‐plane of the unit cell's structure with a dielectric...
This paper reviews and presents design approaches for microwave filter and multiplexers based on resonant-type composite right/left-handed metamaterial. The proposed filter design offers better transmission performances in terms of insertion losses and out-of-band rejection. In addition, it enables substantial tuning to be achieved in the order of over 30 % at the unit-cell's resonant frequency. The...
Electromagnetic metamaterials (MTM) are effectively homogenous structures that are artificially created and not found in nature. Extensive investigation and theoretical analyses by researchers show that this material or structure exhibits simultaneous negative permittivity and permeability phenomenon. Due to the special double negative electromagnetic properties the material was named “left-handed...
