1. A microwave applicator cell for providing microwave energy to a treatment surface comprising:
an exterior sidewall;
an interior sidewall spaced apart from and arranged concentrically within the exterior sidewall;
a central chamber defined within interior sidewall;
a plurality of separating sidewalls extending between the exterior sidewall and the interior sidewall;
a plurality of peripheral chambers defined between the exterior sidewall, the interior sidewall, and the separating sidewalls;
a central microwave generator and waveguide pair configured to direct microwave energy into the central chamber toward the treatment surface; and
a plurality of peripheral microwave generator and waveguide pairs each configured to direct microwave energy into one of the peripheral chambers toward the treatment surface.
