ABSTRACT:
A voltage variable capacitor (VVC) is made by placing an intercalation compound between two electrodes of a capacitor. The VVC has a reservoir of an intercalant in proximity with the intercalation compound. The two materials are chosen from those known to exhibit the intercalation reaction. The extent of the intercalation reaction is controlled by applying a voltage to the intercalant reservoir and the intercalation compound. A variable capacitor is created by applying a signal to the device and appropriately controlling the .di-elect cons. of the device by using the input control voltages.
