1-D EPR imaging of conducting and lossy-dielectric samples

Radiation power absorbed by a half-infinite sample irradiated by microwave field incident normally to the sample surface is calculated. Local properti es of the sample, such as electric conductivity, magnetic susceptibility, c oncentration of localized spins, etc., are supposed to be nonhomogeneous in the direction perpendicular to the surface. In linear on magnetic suscepti bility approximation, algorithms of electron paramagnetic resonance imaging are suggested for the case of conducting and lossy-dielectric materials. T hese algorithms are tested by numerical simulations. Obtained results can b e applied to nuclear magnetic resonance imaging as well.
