At microwave bands, the application of metamaterial-based technologies to enhance the performance of antennas is attractive to both academia and industry. This talk will update the latest progress in developing metamaterialbased technologies for low-profile and broadband antennas at RF and microwave ...
In this paper, a single-layer broadband low-profile ultrathin metamaterial microwave absorber is proposed for wide angle of incidence. The proposed absorber provides triple-band absorption under normal incidence of electromagnetic wave with two peaks lying in X-band and one in Ku-band. The unit ...

To implement a simple, low-loss, and operating in broadband Bessel beam launcher, a novel method of Bessel beam launcher based on GRIN metamaterial lens is proposed here. It has been shown that a well-designed planar GRIN metamaterial lens can transform a point source with spherical wavefront ...
metamaterials capable of providing subwavelength-scale control of optical wavefronts have emerged as an attractive alternative to manipulate guided modes with compact footprints and broadband functionalities. Herein, we propose a universal yet efficient design framework based on the topological metamaterial bu...
