Theoretical analyses on the linear resonant absorption of electromagnetic waves ininhomogeneous plasmas given by various authors are re-examined by numerical com-putation. A set of linearized equations in which collisional and thermal effects of theelectrons are included is solved numerically for a wide range of plasma parameters bydeveloping an implicit difference scheme with e'xtremely small numerical errors. Weare successful to decrease electron temperatures as low as 200 K. It is concluded thatthe Denisov's factor (v./'l coL)"' with a numerical correction can be used tocalculate the peak electrostatic fields at the resonant surface, if his factor is largerthan 20 times the collisional factor v/cta. Here, L is the characteristic length of thedensity gradient and other notations are standard. An empirical formula to calculatethe peak field in the presence of both collisional and thermal effects is proposed.
