Plasma Absorption and Reflection of Electromagnetic Waves Bouguer Law Critical Electron Density

Plasma Absorption and Reflection of Electromagnetic Waves Bouguer Law Critical Electron Density 

The energy flux of electromagnetic waves is determined by the Pointing vector S = eoc [E X B], Taking into account the relation between electric and magnetic fields (ssoE = damping of the electromagnetic oscillations in plasma can be presented 

If the plasma ionization degree and absorption ate relatively low n 1), the absorption coefficient can be simplified and based on equations (3-298) and (3-286) expressed as 

This relation for electromagnetic wave absorption can be presented numerically  

At high frequencies co Ven), the absorption coefficient is proportional to the square of wavelength (/u., a co a therefore, short electromagnetic waves propagate in plasma more readily.
