摘要: We present calculations of the rates decay an excited atom embedded in absorbing dielectric. Decay can occur by spontaneous emission into transverse radiative modes electromagnetic field and Joule heating via longitudinal coupling to The (transverse) rate is modified a dielectric, being free-space multiplied real part refractive index at transition frequency atom. There further modification due difference between macroscopic dielectric local position In addition there which proportional imaginary constant therefore vanishes non-absorbing media. derive expressions for each these discuss physical mechanisms leading them.
