Model of a microwave beam coupling to CO2 laser plasma

Kinetics for the Synthesis of Biodiesel Based on the Calculation of Hot Spot Temperatures in the Catalyst

“…The power generated by the microwave can be evaluated by the following expression: , P mic = P 0 exp ( − 2 α x ) where P mic represents microwave power at any depth from the material surface; P 0 represents the incident microwave flux from the material surface, which was the rated power of microwave reactor; x represents the depth from surface along axial or radial direction, m; α represents the attenuation constant, m –1 , which is expressed by eq , α = 2 π λ 0 0.5 ε ′ ( ( 1 + tan 2 ⁡ δ ) 0.5 − 1 ) where ε′ is the dielectric constant; tan δ is the dielectric loss tangent; λ 0 is the microwave wavelength in vacuum, 0.122 m.…”
