High temperature broadband microwave absorbing materials
Advancements in military and aerospace applications have increased the demand for high temperature microwave absorbing materials. While current state of the art composite material solutions contain strong absorption capabilities, they fail to perform in harsh thermal environments due to thermal limitations of the composite matrix. This work focused on fabricating a ferroelectric-ferrite ceramic composite capable of absorbing electromagnetic energy across a wide range of frequencies and temperatures. The dielectric properties of A-site non-stoichiometric sodium bismuth titanate (NBT) were ...
