1. A method for identifying an electric field, comprising:
locating a gaseous sample in an area, the gaseous sample comprising a component that exhibits a response to a dielectrophoretic force;
transmitting an input signal through the gaseous sample, the input signal including an electromagnetic wave having a wavelength from about 10 picometers to about 100 micrometers; and
analyzing a response signal that is generated upon interaction of the electromagnetic wave with the component, the analysis providing information regarding the presence of dielectrophoretic forces acting on the component, and thereby identifying a static electric field in the area.
