摘要： A resonant coil for nuclear magnetic spectroscopy and microscopy and a method of making the coil are provided. 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. In one aspect of the invention, the current density in the coil is kept constant by providing an inductive element and a set of tapered, interidigitated capacitors having a uniform gap therebetween. The invention maximizes the current-carrying capacity of the coil. The invention further provides a method of making the coil by patterning a film of a conductive material on a substrat into a coil having a lower resonant frequency than the desired frequency of the final coil, placing the coil in an apparatus where it is exposed to increasing current, preferably within a magnetic field such as will be used during operation and finally trimming the coil to the desired resonant frequency trimmed by removal of part of the capacitive element of the coil.
