Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) ...

For at least 151 years, a hemlock and its close neighbor, a red oak, have grown up together on the Bates campus, close enough to overlap branches, while buildings popped up around them. Their survival ...

Abstract: This paper investigates how near-field beamfocusing can be achieved using a modular linear array (MLA), composed of multiple widely spaced uniform linear arrays (ULAs). The MLA architecture ...

Abstract: Although beamforming design enables port-starboard discrimination to some extent, it performs poorly under low signal-to-noise ratio (SNR) conditions and exhibits low port-starboard ...
