Abstract
The cavity antenna model is applied to terahertz passive transmission-line metamaterials based upon metal-insulator-metal waveguides to predict their far-field radiation polarization. The model is verified experimentally by angle-resolved reflectivity spectroscopy of a planar composite right/left-handed metamaterial transmission-line array, which also allows for mapping of the waveguide dispersion.
