Abstract :
The design and testing of several metamaterials that exhibit negative permittivity and negative permeability over microwave frequency bands are presented. A transmission experiment and beam refraction experiment are carried out. The performance, especially the bandwidth of negative refraction, and the losses are compared. The sample fabricated by using a hot-press technique is shown to have a reduced loss.
