Highly Efficient Broadband Millimeter‐Wave–Absorbing Ultrathin Films

Ultrathin film based on a composite of aggregated tetratitanium heptoxide nanocrystals covered by Ga‐Ti‐Co–substituted ε‐iron oxide nanomagnets (Ti4O7@GTC‐ε‐Fe2O3) absorbs millimeter wave with high‐efficiency (99.8%). The cover picture shows that the film behaves like a black hole against millimeter...

Description
Summary:Ultrathin film based on a composite of aggregated tetratitanium heptoxide nanocrystals covered by Ga‐Ti‐Co–substituted ε‐iron oxide nanomagnets (Ti4O7@GTC‐ε‐Fe2O3) absorbs millimeter wave with high‐efficiency (99.8%). The cover picture shows that the film behaves like a black hole against millimeter wave. Further details can be found in the article, number 2001473 by Shin‐ichi Ohkoshi, and co‐workers.
