Abstract
Apparatus for producing and modulating a magnetic vector potential field having a substantially curl-free component. Detection and demodulation of the curl-free component of the magnetic vector potential field using a Josephson junction device are described of the curl-free magnetic vector field. Examples of modulation of the curl-free magnetic vector field suitable for detection and demodulation by the Josephson junction device are disclosed.

Apparatus for generating a modulated curl-free magnetic vector potential field A comprising:
- a configuration of at least one conducting element adapted to generate a magnetic vector potential field surrounding said conducting element configuration when current is applied to said conducting element configuration, a substantial portion of said vector field having a curl-free magnetic vector potential A (defined by CURL A=0) component;
- a current source coupled to said conducting element configuration for applying current thereto;
- and
- modulating means for controlling current from said current source.
A method of generating a modulated curl-free magnetic vector potential field A comprising the steps of:
- (a) configuring at least one conducting element to produce a magnetic vector potential field when current is applied to said at least one conducting element said magnetic vector potential field (A) having a substantial component of said magnetic vector potential field subject to the condition that CURl A=0 (i.e., .gradient.x A=0),
- (b) applying a current to said at least one conducting element;
- (c) modulating said current in accordance with information desired to be transmitted by said curl-free magnetic vector potential field.
