ABSTRACT:
An electrochemical device includes a transparent first electrode and a second electrode distributed in localized areas. An electrolytic solution, disposed between and in electrical contact with the first and second electrodes, contains ions of a metal which can electrodeposit on the first and second electrodes. Atoms of this metal are deposited on the first or the second electrode. A negative electrical potential applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the first electrode, thereby affecting the propagation of electromagnetic radiation through the device. Conversely, a positive electrical potential applied to the first electrode causes deposited metal to be dissolved from the first electrode and electrodeposited from the solution onto the second electrode, thereby increasing the transmissivity of the device.
