Abstract

The subject of magnetic resonance imaging (MRI) is considered and examined from the perspective of a microwave engineer. The static magnetic field and the RF magnetic field are denoted by their field intensities H 0 and H 1 instead of the corresponding flux densities B 0 and B 1. The interaction between these magnetic fields and the material is considered in both the time and frequency domains. One of the assumptions used for simplifying the solution to the problem involves considering the magnetic field as a superposition of a weak time-varying part radiated by the magnetic polarization P (m) only and a much stronger static axially directed one H 0(r).
