Optical Emissions Generated During Ionospheric Heating
… electrons, leading to the production of induced optical emissions. Detection of these emissions yields information regarding wave-plasma interactions, which are of fundamental importance in many physical processes, and provides an effective means of remotely sensing ionospheric constituents and …

Radio and optical studies of natural and artificially stimulated geospace plasmas
Results from radio and optical observations of natural and artificially enhanced geospace plasmas are presented. Firstly, naturally occurring plasma phenomena was studied by means of the radio and optical ground-based instruments and the results are compared with the in-situ satellite measurements. …

Acoustic/Gravity Wave Phenomena in Wide-Field Imaging: From Data Analysis to a Modeling Framework for Observability in the Mlt Region and Beyond
… share the common features of integrating optical emissions or effects on radio waves through deep layers of the atmosphere. The geometry of these integrations create line-of-sight effects that must be understood, described, and accounted for to properly present the measured data in …

Whispering-gallery-mode dye laser emission from liquid in a capillary fiber
The nature of optical whispering-gallery-mode resonances in a layered microcylinder is investigated numerically by studying the scattering characteristics and the internal electromagnetic fields of a normally-illuminated cladded dielectric fiber calculated using the boundary-value method. Computed …

Perception-Aware Optimisation Methodologies for Quantum Dot Based Displays and Lighting
… display power efficiency. The narrow-band optical emissions of QD based devices mixed with their ability to be fabricated through solution processing can be used to mix multiple QDs together to build devices that generate arbitrary spectral shapes. We show how to use this property in an …
