Abstract
An ESR spectrometer is equipped with a split-ring resonator comprising an electrically conductive cylinder or loop which may be excited by a microwave antenna. The conductive cylinder or loop is secured to a surface of an insulating sheet whereby the other surface may be brought to bear upon the specimen being examined. Preferredly, the insulating sheet comprises two insulating sheets with a Faraday shield sandwiched therebetween whereby the magnetic field generated by the microwave energy applied to the loop leaks to the surface of the specimen but the electric field is inhibited.
