LARGE AREA SPRAYING OF TERAHERTZ MATERIALS ON FREE-STANDING BIOCOMPATIBLE SILK FILMS

We report the first large area metamaterials patterned on free-standing biocompatible silk substrates using shadow mask evaporation techniques. The as-fabricated silk metamaterial composites show strong electromagnetic resonant responses at terahertz frequencies, providing a promising path to developing a new class of bioelectric and biophotonic devices.
