It is assumed that the illegal radio, as an example of unknown radio emitter, emits the radio wave with strong enough transmit power covering the area of 1000×1000 m2.
It is easy to demonstrate that for an emitter (or receiver) moving at velocity V in the direction of the receiver (emitter respectively), emitting at frequency F, the frequency modification F d is given by (1).
Accompanying the rear camera is an infrared emitter, constantly emitting an invisible grid across the world, and an infrared camera, picking up the reflections the grid makes.
Edge emitters typically emit from a small spot (or slit) of about 50 µm, have more complex emission pattern and potentially higher output flux than surface emitters.
Alpha-emitters emit high linear energy transfer (LET) α-particles, each causing dense ion pairs (2000 7000) within a relative short path length (50 100 μm) [3].
Carbon nanotube (CNT) as a cold field emitter emits high brightness of electron owing to their high aspect ratio, small radius of curvature, high electric and thermal conductivity, and structural robustness [1, 2].
Under optimized design conditions, a pre-mixed micro-flame stabilizes easily in the micro-emitter, and the heat generated in the micro-emitter is emitted uniformly, providing adequate overall system efficiencies.
This transport mechanism gives rise to the prevailing nomenclature: emitter, which emits or injects carriers, and collector, which collects these carriers injected from a nearby junction.
The dye is excited by a light source (primary emitter) and emits light isotropically.
