The main aim of this study was to apply a classical model for study of non-polar dielectric to achieve a microwave oscillator using electron spin resonance. This dielectric has first been studied in an oscillating electric field in order to find out its electric susceptibility and then its average absorbed power. The transition frequency and the static value of susceptibility have also been found. It has also been deduced that, an electromagnetic wave traversing this dielectric is obeying an exponential law. In order to achieve a microwave oscillator, the sample has been considered in an oscillating magnetic field. An external magnetic induction, perpendicular to oscillating magnetic field has been applied to see how the Zeeman level could split into two sub-levels. The distribution of populations over these two sub-levels has also been determined. Finally, the sample containing lithium atoms as impurities was placed in a cavity resonator, tuned on the resonance frequency of the sample. It was found out that the sample was emitting an average power instead of absorbing, when the magnetic induction was switched from +B0 to -B0 |
