Patent for a Heat-Resistant Ceramic for Wireless Signal Transmission
ECE University Distinguished and William Lincoln Smith Professor Vincent Harris was awarded a patent for developing a “Ceramic frequency selective surface.”
Abstract Source: USPTO
An all-ceramic frequency selective surface (ACFSS) material is provided for use in high temperature environments where there is a need for selective transmission of a defined wavelength band of electromagnetic radiation through the material. Unlike traditional frequency selective surfaces that use metals to form a structured or patterned layer that defines the passband, the present ACFSS material uses electrically conductive ceramic materials to form the patterned layer, giving the material a much greater heat stability than metal-containing frequency selective surface materials.
