The 50% peak absorption predicted for resonant absorption in a linear density profile can be raised to above 90% if a different profile is used which involves a sharp jump in density along which a surface wave may propagate. Collisionless-plasma simulation studies show that at high intensities the energy goes into fast electrons which are accelerated back out of the plasma into the vacuum.
