Abstract
A resonant coil for nuclear magnetic spectroscopy and microscopy is provided, in which the coil is in the form of nested, interrupted loops of a conductive material forming a distributed inductive element and having a plurality of capacitive elements with capacitance distributed over the periphery of the loops. The coil is preferably formed as a thin film of a superconductive material on an electrically nonconductive substrate.
Claims7
An RF coil comprising:
- (a) a planar dielectric substrate;
- (b) a thin film of conductive material deposited on the substrate, the conductive material forming a plurality of nested loops in essentially a single plane;
- each of the loops being interrupted by a nonconductive area defining a gap;
- adjacent loops being so nested that the gap of any one loop is not proximately disposed to the gap of an adjacent loop;
- each loop having a first finger and a second finger, a finger being defined by a portion of the loop disposed between adjacent gaps of the coil;
- whereby the loops form an inductive element and the first finger of one loop forms a capacitive element with an adjacent finger of another loop.
