The electromagnetic absorbers based nano - structured granular polymer-composites at gigahertz frequencies.

The rapid increase in electromagnetic interference has received a serious attention from researchers who responded by producing a variety of radar absorbing materials especially at high gigahertz frequencies. Ongoing investigation is being carried out in order to find the best absorbing materials which can fulfill the requirements for smart absorbing materials which are lightweight, broad bandwidth absorption, stronger absorption etc. Therefore, this article introduces the electromagnetic wave absorption mechanisms and then reveals and reviews those parameters that enhance the absorption performance.

Hollow MOF-Derived CoNi/C Composites as Effective Electromagnetic Absorbers in the X-band and Ku-band

Metal organic frameworks (MOFs) derivatives have received extensive attentions in the field of microwave absorption due to their unique advantages and various properties. In this work, cubic hollow CoNi/C composites...

The Smallest Anions, Induced Porosity and Graphene Interfaces in C12A7:e- Electrides: A Paradigm Shift in Electromagnetic Absorbers and Shielding Materials

Advanced conducting ceramics with desirable high-frequency electromagnetic responses are essential to function as fifth-generation (5G) microwave absorbing and shielding materials in harsh environments. Mayenite electride (C12A7:e-) is a room-temperature stable...
