Abstract
A system for modifying the radiant energy spectrum of a thermal energy source to produce a desired spectral bandwidth profile including a frequency-selective resonant micromesh filter (50) confronting a thermal energy source (80). Micromesh filter (50) includes an array of resonant-conductive antenna elements (50', 50') and a substrate (56) for supporting the antenna elements. Thermal radiation (82) emitted from energy source (80) is filtered by micromesh filter (50), wherein radiant energy at particular wavelengths is reflected back to the energy source, while certain wavelength photons are transmitted through the micromesh filter.
