Calculation and response of SNMR excitation field excited by square coil

摘要

at present nuclear magnetic resonance studies in our country focus on the application. It is mainly to study the detection of the effect of groundwater in different geological conditions. Researching in the theory, there are only a few articles on studying of one-dimensional forward modeling and inversion, filtering and frequency offset. Forward in Square Coil is empty stage in our country. According to principle of superposition, calculation the electromagnetic response of a square coil expression.Then further calculate the vertical field, toppled the angle, and the nuclear function. End up with a one-dimensional response to SNMR.
