Abstract
An encoder includes a layered structure including a metal plate, a dielectric layer arranged on the metal plate, and a plurality of metallic components arranged on the dielectric layer to form a pattern of resonant circuits. The encoder includes an emitter to emit a waveform of a resonant frequency to the layered structure and a receiver to measure amplitudes of the waveform reflected from the layered structure. The processor operatively connected to a memory storing data relating positions of the emitter with amplitudes of the reflected waveform determines a position of the emitter from the measurements of the amplitudes based on the data. The encoder includes an output interface to render the position of the emitter.
