Experimental Investigation of a Power Divider Based on Microstrip and Metamaterials with L-C Lumped-elements

One-dimensional metamaterials, using L-C lumped-elements, have a broad left-handed passband, with anti-parallel phase and group velocities. Power dividers, with symmetric and asymmetric structures, are proposed. They are composed of conventional micros...

Metamaterials ,1,2 with simultaneous negative permittivity and permeability, are promising materials for new types of microwave components. In metamaterials, the waves are propagating with anti-parallel phase and group velocities, as demonstrated by backward waves. 3 Recently, an extended transmission-line approach to metamaterials, low loss and broadband structures was proposed...
