Resonant frequency filtered arrays for discrete addressing of a matrix. Applications include, for example, but are not limited to, flat panel displays, transparent displays, charge-couple devices, electronic paper, printing, heated pixel arrays, chemical catalysis, accelerated polymerization, sensors, rapid prototyping, manufacturing, digital cameras, telescopes, image recording, microscopy, memory chips, selective high density radio signal routing, touch screens, index tables, robotic tactile sensors, acoustical mapping, radio frequency identification, sound filtering, audio recording, amplification, sound wave direction sensors, sound source identification, motion detection, and integrated circuits. The matrix can include a substrate and intersecting frequency filtered arrays of electrical conducting traces. Each of the electrically conducting traces is associated with a frequency of alternating current. A material is located between intersections between the frequency filtered arrays. The material changes a property in response to a stimulus received from the arrays or a source other than the arrays.
