Abstract
Antenna means are provided for mapping a static magnetic field comprising an array of impedence matched untuned antenna elements with linear dimensions greater than several wavelengths of radio frequency used for nuclear magnetic resonance (NMR) or electron spin resonance (ESR). The antenna elements comprise one or more electrical conductors housed within and electrically insulated from a solid shield surrounding the conductor(s). The solid shield contains a void volume filled with a sample adapted for use in NMR or ESR.
