The rising levels of carbon dioxide emissions stemming from the combustion of fossil fuels necessitate immediate attention to implement sustainable energy solutions. Hydrogen as a fuel, holds significant potential for establishing CO2-neutral systems, and the utilization of microwave pyrolysis of...

At radar frequencies, the propagation speeds and attenuations of electromagnetic (EM) waves are controlled by the complex dielectric permittivity. Consequently, the real and imaginary components as well as their variation with frequency are important parameters necessary for properly interpreting...
