Abstract :
Whistler wave excitation in a laboratory magnetoplasma containing a cylindrically symmetric density depletion duct is studied. Using a rigorous solution for the total source-excited field, the radiation resistance of a circular loop antenna located in such a duct is determined. Conditions are found under which the radiation resistance of the loop antenna in a nonuniform density depletion duct can be notably greater than that in a homogeneous magnetoplasma whose parameters coincide with those near the duct axis or outside the duct.
