  • Abstract
    Characteristics are described of a novel probe sensitive to the amplitude and phase of the radio-frequency magnetic field which is composed of a laser diode linked with a small loop antenna, an optical fiber, and a phase-sensitive detection instrument. The probe is highly sensitive and is radio-frequency interference free. The minimum detectable radio-frequency magnetic field is 10 μA/cm (38 nW/cm2in power density).
