AbstractVolcanic jet flows in explosive eruptions emit radio frequency signatures, indicative of their fluid dynamic and electrostatic conditions. The emissions originate from sparks supported by an electric field built up by the ejected charged volcanic particles. When shock-defined, low-pressure regions confine the sparks, the signatures may be limited to high-frequency content corresponding to the early components of the avalanche-streamer-leader hierarchy. Here, we image sparks and a standing shock together in a transient supersonic jet of micro-diamonds entrained in argon. Fluid dynamic and kinetic simulations of the experiment demonstrate that the observed sparks originate upstream of the standing shock. The sparks are initiated in the rarefaction region, and cut off at the shock, which would limit their radio frequency emissions to a tell-tale high-frequency regime. We show that sparks transmit an impression of the explosive flow, and open the way for novel instrumentation to diagnose currently inaccessible explosive phenomena.

Noise Amplifier

The present world is ruled by wireless communication. From a telephone communication to satellite communication, the word “wireless” plays a major rule. In the recent years, the modem wireless communication in broadcast and microwave radio demands the properly designed Low Noise Amplifier (LNA) in receiver front ends for proper communication. The paper presents the design of high performance low noise amplifier at radio frequency regime. The LNA is implemented at operating frequency of 1.6 GHz and 2.6 GHz has been implemented at .18um CMOS process. LNA are regularly used in wireless communication receiver leading-ends due to their equity to intensify shaky Radio Frequency (RF) signals without summing additional noise. Cadence virtuoso tool has been used to implement the LNA design and the performance parameters are analyzed at operating frequency.
