Special Issue Information
Dear Colleagues,
Nowadays, electronic information technology is playing a prominent role in stealth fighters, electromagnetic countermeasures, wireless communications and electromagnetic pollution protection, which results in the EMI (electromagnetic interference) and pollution have also become significant problems. Therefore, the design of high-performance electromagnetic wave absorbing and shielding materials that can be widely used in the microwave frequency band (0.2–20 GHz) has become a key issue to be solved urgently.
Generally, EMI shielding refers to a shield that blocks the propagation of electromagnetic waves in the transmission path by impedance mismatch, which results some electromagnetic waves are directly reflected and other are absorbed by the interaction of electric or magnetic dipoles in a conductor material with the electromagnetic field. Traditional EMI shieding materials mainly metal-based, carbon-based and conductive polymers. In contrast to EMI, EMA (electromagnetic wave absorbing) materials allow electromagnetic waves to be incident into the material and then effectively attenuate it through dielectric loss, magnetic loss and phase interference. Traditional absorbing materials mainly include ferrite, ceramic, conductive polymers, carbon-based composites, etc. Whether EMI or EMA materials, single material are limited by high density, complex preparation methods, low absorption efficiency, or poor environmental applicability. And their derivative materials are difficult to meet the basic requirements of advanced absorbing materials, including high absorption efficiency, wide absorption bandwidth, light-weight and thin thickness. In order to provide the readers with some perspectives of the latest progresses in the developments and applications of electromagnetic wave shielding and absorbing materials, this Special Issue will collect the papers reporting the current status of electromagnetic functional materials, including but not limited to the following:
- Original research articles related to the design and preparation of high-performance EMI and EMA materials.
- EMI and EMA materials based on advanced manufacturing methods.
- Novel mechanism on EMI and EMA materials.
- In-depth analysis of electromagnetic loss mechanism on EMI and EMA materials.
- Review articles on the latest research progress of EMI and EMA materials.
