Active absorption of electromagnetic pulses in a cavity

Electromagnetic Waves in Cavity Design

Understanding electromagnetic wave phenomena is very important to be able to design RF cavities such as for atmospheric microwave plasma torch, microwave vacuum oscillator/amplifier, and charged-particle accelerator. This chapter deals with some electromagnetic wave equations to show applications to develop the analytic design formula for the cavity. For the initial and crude design parameter, ...

Electromagnetic absorption and structural properties of SrFe11.98Mg0.1Sn0.1O19/BaTiO3 nanocomposites

In this research, first, nanoparticles of SrFe11.98Mg0.1Sn0.1O19 hexaferrite was synthesized via sol-gel auto-combustion process and then the nanocomposites of hexagonal ferrites/perovskite with the amounts of SrFe11.98Mg0.1Sn0.1O19/BaTiO3 (50/50, 40/60, 70/30 w/w) was prepared by the ball-milling...

Absorption of ultrashort optical pulses in water.

We investigate the linear propagation of 800 and 1530 nm ultrashort optical pulses in water. For all pulse repetition rates studied, we observe pure exponential decay down to a transmission of 2.5 x 10(-5). We further demonstrate that previous observations of nonmonoexponential decay and pulse splitup in broadband pulses are consistent with Beer's law in the purely linear regime.

Transmission and Attenuation of Electromagnetic Pulses

Given a signal source outputting a series of pulses, one may wish to measure the pulses’ rate, distribution of amplitudes, occurrence times relative to other pulses, etc. Such measurements are done with oscilloscopes, multichannel analyzers, amplifiers, discriminators, coincidence circuits, etc., which may or may not be working properly. It is essential, therefore, to gain facility in the use o...
