Abstract:
1. A variable capacitor (varactor), comprising: a solid dielectric having two opposing sides, with an integrally attached charged electrode on one side of the dielectric and the exposed other side having a dielectric molecular boundary; a conformal electrode having an opposite charge than the integrally attached electrode, said conformal electrode being in an initial fluid or molten state and being melted onto the exposed other side of the dielectric, to establish a conformal electrode molecular boundary that substantially conforms to said dielectric molecular boundary when said conformal electrode solidifies, and being removably displaceable from the dielectric; a guide extending through both the conformal electrode and the dielectric, providing substantially perpendicular alignment of the conformal electrode with the other side surface of the dielectric during movement; and a displacement mechanism coupled to either the conformal electrode or to at least one of the dielectric and attached electrode, providing displacement substantially perpendicular to a junction of the conformal electrode and dielectric surface, wherein a capacitance is varied by displacing the conformal electrode from a surface of the exposed side of the dielectric.
