Acoustic Leaky-Wave antenna

open access: yes2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2014
In the last years, the number of studies carried out in the field of acoustic metamaterials has significantly increased. In year 2009, our group proposed a concept of acoustic composite right/left hand transmission line (CRLH-TL) metamaterial, consisting of a waveguide periodically loaded with membranes along the duct, and transverse open channels ...

A Review of Reconfigurable Leaky-Wave Antennas [PDF]

open access: yesIEEE Access, 2021
A comprehensive survey of the reconfigurable leaky-wave antennas (LWAs) is made in this paper. Beam-steering and unique radiating features of LWA are highlighted particularly. Therefore, the radiation mechanism of different types of LWA, including uniform, quasi-uniform, periodic, and metamaterial LWAs are discussed in detail.
