Theoretical studies of ordinarily polarized surface waves at the first andsecond harmonics of the ion and electron cyclotron frequencies propagatingacross an external steady magnetic field are carried out in the case of a weakplasma spatial dispersion along the normal direction towards the plasmainterface when the penetration depths of these waves are much greater than theLarmor radii of plasma particles. These waves are eigenmodes of the planarplasma-dielectric layer-metal waveguide structure which is placed into asteady magnetic field oriented parallel to the plasma surface. Theireigenfrequencies can be either greater than or less than the correspondingharmonics of the ion or electron cyclotron frequencies under differentconditions in the waveguide considered. The dependence of their damping ratescaused both by collisions between plasma particles and the resonantplasma-wave interaction on the waveguide structure parameters is alsostudied. A comparison of the collisional damping with the collisionlessdamping is carried out for these modes. To illustrate the possibility ofplasma periphery heating by these modes, the flow of their wave power andthe quantity of the absorbed wave power are calculated.
