Abstract
The embodiments include an array in intimate adjacent contact with a substrate foundation. The array has a plurality of radio frequency (RF) witness films overlain on the substrate foundation. Each RF witness film is a unit cell defined in a three-dimensional coordinate frame of reference, and is centered at an origin of the three-dimensional coordinate frame of reference. Each RF witness film in the plurality of RF witness films is equally-spaced from adjacent RF witness films.
