  It is shown that stationary vortex structures can be excited in a ferrite
film. This is the first proposal for creating vortex structures in the
important cm and mm wavelength ranges. It is shown that both linear and
nonlinear structures can be excited using a three-beam interaction created with
circular antennae. These give rise to a special phase distribution created by
linear and nonlinear mixing. An interesting set of three clockwise rotating
vortices joined by one counter-rotating one presents itself in the linear
regime: a scenario that is only qualitatively changed by the onset of
nonlinearity. It is pointed out that control of the vortex structure, through
parametric coupling, based upon a microwave resonator, is possible and that
there are many interesting possibilities for applications.
