About this Research Topic
Electromagnetic pollutions are recently known as a global concerns In particular, the military fields including radars, microwave weapons, and so on have augmented these pollutions. Thus, electromagnetic interference shielding and microwave absorbing materials have been abundantly architected, mitigating the electromagnetic adverse effects, and widely used in stealth technology.
The permeability and permittivity of microwave absorbing structures are the pivotal parameters paving the way for their microwave attenuating capability. Polarization and conductive loss play the vital role in tuning microwave absorbing characteristics. Accordingly, diverse dielectric structures have been tailored performing based on their dipole, interfacial, and defect polarization as well as electric conductivity consisting of oxide, sulphide, and metal nanostructures and conductive polymers. Till date, various efforts have been done to improve efficient absorption bandwidth (reflection loss>10dB), maximum reflection loss, costs, absorber thickness and density, as well as experimental scenario.
This Research Topic aims to cover promising, recent, and novel research trends in the dielectric microwave absorbing structures. The novel prospects of developing the microwave attenuating ability of dielectric microwave absorbers and promoting the commanding mechanisms comprising impedance matching are pleasant. Areas to be covered in this Research Topic may include, but are not limited to:
Microwave absorbing structures based on:
• Two dimensional (2D) Carbides and Nitrides (MXenes) structures and composites
• Metal–organic frameworks (MOF)-derived materials
• Conductive polymers and their composites
• Aerogels
• Defect and morphology manipulating
• Dielecteric nanoparticles and composites
• Biomass derived materials
