Metamaterials enable precise tailoring of light–matter interactions at the subwavelength
scale, permitting access to the full range of electromagnetic responses encoded in Maxwell's …

Terahertz (THz) science and technology have greatly progressed over the past two decades
to a point where the THz region of the electromagnetic spectrum is now a mature research …

Imaging in the terahertz (THz) range of the electromagnetic spectrum is difficult owing to the
lack of high-power sources and efficient detectors. For decades, there has been tremendous …

High-resolution and hyperspectral imaging has long been a goal for multi-dimensional data
fusion sensing applications–of interest for autonomous vehicles and environmental …

Analytical chemists are instilled with the Shannon–Nyquist theorem for measuring practices:
the sampling frequency must be greater than two times the frequency of the signal of interest …

We propose and experimentally realize the concept of frequency-division-multiplexed single-
pixel imaging. Our technique relies entirely on metamaterial spatial light modulators, the …

A method of active terahertz imaging based on compressive sampling is demonstrated. A
metal mask structure is designed with all modulation matrices engraved on. The imaging …

Electromagnetic metamaterials consist of two or three dimensional arrays of tailored metallic
and/or dielectric inclusions and provide unprecedented sub-wavelength control over light …

A metamaterial perfect absorber having a hybrid layer and total thickness of 50 nm is
demonstrated in this paper. The results indicate that a broadband absorption above 90% is …

Diffractive optics has long served as the basis of spectroscopic measurements of materials.
Operation in the resonance domain further allows these elements to achieve high efficiency …
