Abstract
In an electrostatic device for the gating of electromagnetic radiation in response to an electrical signal, including a fixed and a resilient variable electrode with a film of insulation interposed therebetween, the variable electrode lies adjacent to the fixed electrode defining a line of tangency therebetween. The position of mounting of the variable electrode is spaced from the line of tangency and in this space the variable electrode has a curved portion that minimizes wrinkles therein and provides a lower and more predictable sensitivity. Furthermore, the assembly of such devices tends to become less critical and simpler.
