TL;DR: In this article, the authors demonstrate tuning of a metamaterial device that incorporates a form of spatial gradient control, achieved through a vanadium dioxide layer which interacts with an array of split ring resonators.
Proceedings ArticleDOI
The development of indirect microwave holography for measurement and imaging applications
TL;DR: In this paper, the basic theory of indirect holography and how it relates to optical holographic techniques is described. But the basic theoretical framework is not discussed. And the authors do not discuss the use of indirect Holographic techniques for microwave measurements and imaging.
Journal ArticleDOI
Ku-Band Suspended Meshed Patch Antenna Integrated with Solar Cells for Remote Area Applications
TL;DR: In this article, a dual-band suspended microstrip meshed patch antenna integrated with a polycrystalline silicon solar cell for Ku-band satellite applications is proposed and presented, which covers the operating frequency range from 11.7GHz to 12.22 GHz downlink band and from 14.0GHz to 14.5GHz uplink band allocated by the ITU to the Regions 1 and 2.
Journal ArticleDOI
Resonant crystal band gap metamaterials in the microwave regime and their exotic amplification of evanescent waves
TL;DR: In this paper, the authors realize resonant crystal band gap metamaterials using circuit structures in the microwave regime, which behave quite differently from the conventional photonic band gap structures.
