03 January 2022 Current Affairs:Subodh G, an assistant professor at Kerala University, and Vidhya Lalan, a research scholar, have created fifth-generation microwave absorbers.

Highlights:
  • The development of 5G microwave absorbers could be used as a shield against electromagnetic radiation.
  • Because of the worldwide quest for smarter and advanced electronic devices, the threat of electromagnetic pollution and radiation is unavoidable.
  • Electromagnetic interference (EMI) has an impact on high-end devices and is harmful to live organisms' health.
  • The 'mayenite electrode’ is the new shielding material. Chemically, it is inert. In the high-frequency region, particularly in the 5G band, the material has demonstrated exceptional microwave absorption ability.
  • This compound has a high conductivity due to the presence of anionic electrons, which is responsible for its high electromagnetic wave attenuation.
  • The Mayenite electrode is highly porous and has a graphene coating, in addition to its conductivity.
  • Because of the existence of macropores and graphene functionality in this material, electromagnetic waves are reflected and then absorbed repeatedly.
  • In the extreme high-frequency region, the material exhibits microwave attenuation. It emphasizes the material's ability to be used in futuristic devices for 5G applications.
  • The study of mayenite electride was carried out as part of Kerala University's 'Microwave Materials Laboratory scheme.'
Significance
  • In this age of 5G technological advances of Things, the problems caused by EMI require immediate attention (IoT). 
  • This is as it has become increasingly difficult to complete repetitive tasks without the use of electronic devices and the internet, both of which rely on electromagnetic waves. 
  • As a result, the advancement of 5G microwave absorbers is critical for applications that occur frequently.
