Journal ArticleDOI
Bandgap and optical transitions in thin films from reflectance measurements
TL;DR: In this paper, a new formulation and method are presented for evaluating bandgap, optical transitions and optical constants from the reflectance data for films deposited onto a non-absorbing substrate, which can be used to evaluate the optical properties of the films.
Journal ArticleDOI
A Compact Dual-Band Dual-Polarized Omnidirectional Antenna for On-Body Applications
TL;DR: In this article, a dual-band dual-polarized wearable antenna for on-body communication in the 2.45 and 5.8 GHz ISM bands is presented.
Journal ArticleDOI
A Miniaturized Ring Slot Antenna Design With Enhanced Radiation Characteristics
TL;DR: In this paper, a miniaturized CPW-fed ring slot antenna using interdigitated slits was presented, and the antenna characteristics of the electrically small antenna were enhanced using a low impedance metamaterial slab design working under normal incidence.
Journal ArticleDOI
Some aspects of surface roughness in polycrystalline thin films: optical constants and grain distribution
TL;DR: A modified formulation and new method have been suggested to derive meaningful information on the optical constants, grain size and grain distribution of polycrystalline thin films where surface roughness plays an important part through the contributions arising out of scattered transmission and diffuse reflection.
Journal ArticleDOI
Compact Circularly Polarized Wide-Beamwidth Fern-Fractal-Shaped Microstrip Antenna for Vehicular Communication
TL;DR: A compact circularly polarized wide-beamwidth patch antenna that can capture signals from a wide elevation angle and a complete azimuth range to cover the entire blind spot zone is presented here.
