Here we present the demonstration of a single-negative all-dielectric metamaterial that possesses peak reflectance over 99% and an average reflectance over 98% across a 200 nm wide bandwidth in the short-wavelength infrared region.
Oceans & space publications
Measurements have been combined with all-sky images, polar convection measurements, and FAST particle and field measurements to quantify the contribution of different magnetosphere-ionosphere coupling processes to the extraction efficiency of ions from the ionosphere.
Ferromagnetic Heusler Co2FeAl0.5Si0.5 epitaxial thin-films have been fabricated in the L21 structure with saturation magnetizations over 1200 emu/cm3.
In this study we demonstrate that over a 3 year period, ionospheric variability observed from Poker Flat, Alaska, has, in fact, a high degree of long-term predictability.
Distributed Coverage with Mobile Robots on a Graph: Locational Optimization and Equal-Mass Partitioning
This paper presents decentralized algorithms for coverage with mobile robots on a graph. We use distributed vertex substitution for locational optimization and equal mass partitioning, and the controllers minimize the corresponding cost functions.
Characteristics of Large-Scale Wave Structure Observed from African and Southeast Asian Longitudinal Sectors
In this scenario, a comprehensive study is carried out, for the first time, on the spatial and temporal characteristics of LSWS observed in spatial domain over African and Southeast Asian longitudinal sectors during the year 2011.
Comparison of MODIS 3 Km and 10 Km Resolution Aerosol Optical Depth Retrievals over Land with Airborne Sunphotometer Measurements During Arctas Summer 2008
In this paper we compare MODIS and AATS AOD at 553 nm in 58 10 km and 134 3 km retrieval grid cells.
This paper provides a range of alternatives for analysts when dealing with geo-spatial data addressing activities in science, technology and innovation.
Horizontal Parameters of Daytime Thermospheric Gravity Waves and E Region Neutral Winds over Puerto Rico
We report on the electron density perturbation amplitudes, periods (up to 60 min), horizontal and vertical wavelengths, phase speeds, and propagation directions of daytime traveling ionospheric disturbances (TIDs) from 115 to 300 km altitude using dual-beam experiments at the Arecibo Observatory (AO), Puerto Rico.
