1. A system for making a quantitative measurement of an electric field, comprising:
- a plurality of antennas separated from one another by known distances, said plurality of antennas arrayed in a region that extends in at least one dimension;
means coupled to said plurality of antennas for measuring a voltage difference between at least one selected pair of antennas from said plurality of antennas; and
a processor coupled to said means for measuring, said processor dividing each said voltage difference by one of said known distances associated with said selected pair of antennas corresponding thereto to thereby generate a resulting quantity with a plurality of resulting quantities being thereby defined over said region to quantitatively describe an electric field therein.

Abstract
A method and system are provided for making a quantitative measurement of an electric field. A plurality of antennas separated from one another by known distances are arrayed in a region that extends in at least one dimension. A voltage difference between at least one selected pair of antennas is measured. Each voltage difference is divided by the known distance associated with the selected pair of antennas corresponding thereto to generate a resulting quantity. The plurality of resulting quantities defined over the region quantitatively describe an electric field therein.

20. A method of making a quantitative measurement of an electric field, comprising the steps of:
-
using at least one antenna to sense voltage differences between known locations in a region that extends in at least one dimension; and dividing each of said voltage differences by a distance between two of said known locations associated therewith to thereby generate a resulting quantity with a plurality of resulting quantities being thereby defined over said region to quantitatively describe an electric field therein. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
