Web17 aug. 2016 · By my interpretation, the relationship between the frequencies and wavelengths of e.m. waves (and hence the speed of light) is dictated by the relationship between electric and magnetic fields, which is in turn dictated by Vacuum Permittivity, which I believe (possibly in error) to be an inherent property of our universe. Web14 apr. 2024 · The development of advanced and efficient P-band radar absorbing materials has become a key research direction in the field of wave absorption. However, there are fewer studies to evaluate the electromagnetic properties of these materials. Peng measured the complex permittivity of P-band materials using a re-entrant coaxial cavity. …

Web8 jun. 2024 · 2 Answers. Permittivity just means how easily the electric field can exert influence over the space. The higher the the permittivity the harder is for electric field to exert force on a charge at fixed difference away. A vacuum has the lowest permittivity which means that electric field function best in vacuum.
