Abstract
In a unilateral NMR probe for the analysis of a material comprising at least one magnet for generating a constant time-invariant polarization field Bin the material to be analyzed and current conductors forming a radio frequency oscillation circuit for generating a pulsed radio frequency magnetic excitation field Bwhich is superimposed on the polarization field Nin the material, the circuit conductors are so designed as to provide several adjacent excitation fields Bwith alternatingly oppositely oriented magnetic fields, whereby the current conductors generating each one of the excitation fields have a distance from each other which causes a certain penetration depth in the material to be analyzed and echoes received therefrom provide measurement values which are characteristic for the material being analyzed.
