Experimental demonstration of Luneburg lens based on hyperuniform disordered media
(AIP Publishing LLC, 2019-02-04)
Hyperuniformity provides a means of categorizing many nanostructures including nano-composite materials, and the design methodology based on hyperuniform randomness often leads to devices with extraordinary characteristics. ...
Polar nano-clusters in nominally paraelectric ceramics demonstrating high microwave tunability for wireless communication
(Elsevier, 2020-04-19)
Dielectric materials, with high tunability at microwave frequencies, are key components in the design of microwave communication systems. Dense Ba0.6Sr0.4TiO3 (BST) ceramics, with different grain sizes, were prepared in ...
Extraordinary Directive Emission and Scanning from an Array of Radiation Sources with Hyperuniform Disorder
(American Physical Society, 2021-01-01)
The main challenge in the antenna or laser array design is to find the element distribution that best meets the optimal performance for broadband emission and large angle beam steering. In the past, the design strategy was ...
