Abstract
A charge storage device having a capacitance that is variable by alteration of the relative permittivity of the dielectric positioned between conductive electrodes within the device. The device consists of two conductive plates sandwiching a conductive grid, typically embedded within a dielectric material. Charging the grid with a negative or positive potential changes the value of the dielectric constant (the relative permittivity) and thereby changes the capacitance of the device.
Claims10
An electronic component device for receiving and storing an electrical charge, the device comprising:
- a first plate capable of storing a charge therein, said first plate in electrical contact with a first conductor terminal;
- a second plate capable of storing a charge therein, said second plate spaced apart from said first plate and in electrical contact with a second conductor terminal;
- a dielectric material occupying the space between said first and second plates;
- a grid capable of storing a charge therein, said grid positioned between said first and second plates within said dielectric material;
- and
- means for charging said grid.
An impedance matching circuit in operative association with a transmission line or wave guide, the circuit comprising:
- a variable capacitor including a first plate capable of storing a charge therein, in electrical contact with a first terminal of a source of power distribution;
- a second plate, spaced apart from the first plate and in electrical contact with a second terminal;
- a dielectric material occupying the space between the plates;
- a grid between the plates;
- and
- a means of varying the charge on the grid;
- wherein the charge on the grid is adjusted so that the impedance of the circuit matches the impedance of the transmission line or wave guide.
