Abstract: | Penetration of longitudinal and transverse fields into a semi-infinite collisional plasma with fractionally accommodating boundary, having specular and diffuse reflecions is studied. The penetration of longitudinal field was studied by Landau and recently by Mason which was extended for transverse waves by Gupta and Varma. The theory is extended for collisions between electrons and ions according to B.G.K. Model, and its resemblence with metals for electrons and holes, gives its practical significance. The reflection coefficients and surface impedence are observed. The results are compared with non-collisional cases and it is observed that depth of penetration for collisional plasma decreases. |
