Fischer custom communications, inc. Proposes to design and fabricate electric and magnetic field sensors to operate over the 10 khz - 1 ghz frequency range. The electric field sensors will be capable of sensing electric fields in the range of .01 v/m to 150 kv/m. The magnetic field sensors will be capable of sensing magnetic fields in the range of 0.1 ma/m to 800 a/m. Each sensor will output a voltage proportional to the measured field and will work into a 50 ohm load impedance. The sensors for fabrication will use proven methodology and component structures. Fischer custom communications, inc. Will also provide design conception of a new technology sensor using and entirely fiberoptic approach. This sensor composed entirely of dielectric material will not perturb the fields it is sensing.
