| Outline of Final Research Achievements |
Sensors of electromagnetic fields traditionally consist of antenna elements that are made of metal. A common concern of this type sensor is perturbation of the electromagnetic field by the measurements.
We have recently studied a new type of electromagnetic-field sensor based on quantum phenomena, in which metal antenna elements are not employed.This new sensor has a glass cell that holds a gas of cesium-133 atoms instead of the metal antenna elements ordinarily required by electromagnetic-field sensors. The perturbation of an electromagnetic field being measured by the 133Cs-based sensor is thus expected to be lower than that by a metal-antenna-based sensor.
We studied on an initial examination of a new type electromagnetic field meter based on quantum phenomena without any metal antenna element.
