We present the design of a tunable metamaterial element that can serve as the building block for a dynamically reconfigurable aperture. The element-a complimentary electric-LC (cELC) resonator-is patterned into the upper conductor of a microstrip tra

Active metamaterials have been used to realize terahertz imaging with a single-pixel detector. Compressive techniques permit high-fidelity images to be acquired at high frame rates. The technique involves no moving parts and yields improved signal-to

We analyze the properties of complementary metamaterials as effective inclusions patterned into the conducting walls of metal waveguide structures. We show that guided wave metamaterials can be homogenized using the same retrieval techniques used for

Compressed Sampling It is often said that a picture is worth a thousand words. But images often contain a lot of redundant information—effectively creating huge data files of meaningless information. While algorithms can compress the size of a file

In the current study individuals with a history of drug abuse (users of heroin, cocaine, or amphetamine) displayed a 13-100% increase in body weight (self-reported) and exhibited a trend toward insulin resistance. Therefore, we investigated the effec

Imaging in long wavelength regimes holds huge potential in many fields, from security to skin cancer detection. However, it is often difficult to image at these frequencies – the so called ‘THz gap1’ is no exception. Current techniques generall

A metamaterial aperture operating as a leaky waveguide with resonating metamaterial irises can sweep its operation frequency to modify its complex field pattern with no moving parts. By randomly distributing the metamaterials' resonance frequencies,
