How do ceramic fibers react with electromagnetic radiation at high frequencies?

Ceramic fibers, depending on their composition, can exhibit different reactions to high-frequency electromagnetic radiation. Generally, they can either absorb, reflect, or transmit these high-frequency waves. Some ceramic materials are designed to be transparent to certain frequencies, allowing them to pass through with minimal interaction. Others, particularly those with high dielectric properties or those that are conductive, can absorb or reflect the radiation. The specific response is influenced by factors such as the fiber's chemical composition, microstructure, and the frequency and intensity of the electromagnetic radiation. In applications like radar or microwave technology, ceramic fibers may be engineered to have specific electromagnetic properties to either shield against or enhance the transmission of high-frequency signals.
