GLOBAL OBSERVATIONS OF ELECTROMAGNETIC AND PARTICLE ENERGY FLUX FOR AN EVENT DURING NORTHERN WINTER WITH SOUTHWARD INTERPLANETARY MAGNETIC FIELD

Global observations of electromagnetic and particle energy flux for an event during northern winter with southward interplanetary magnetic field

The response of the polar ionosphere–thermosphere (I-T) system to electromagnetic (EM) energy input is fundamentally different to that from particle precipitation.To understand the I-T response to polar energy input one must know the intensities and spatial distributions of both EM and precipitation energy deposition.Moreover, since individua

Efficiency droop suppression of distance-engineered surface plasmon-coupled photoluminescence in GaN-based quantum well LEDs

Ag coated microgroove with extreme large aspect-ratio of 500:1 was fabricated on p-GaN capping layer to investigate the coupling behavior between quantum wells and surface plasmon in highly spatial resolution.Significant photoluminescence enhancement was observed when the distance between Ag film and QWs was reduced from 220 nm to about 20 nm.A max

Couplants in Acoustic Biosensing Systems

Acoustic biosensors are widely used in physical, jumbo gourmet tava chemical, and biosensing applications.One of the major concerns in acoustic biosensing is the delicacy of the medium through which acoustic waves propagate and reach acoustic sensors.Even a small airgap diminishes acoustic signal strengths due to high acoustic impedance mismatch.Th
