A cut-off tubular housing has flat surfaces for mounting multiple solid state microwave oscillators using microstrip circuitry, each exciting a wire-like resonant coupler wound on a central dielectric support tube for receiving a frankfurter or other material body. The couplers are longitudinally spaced and angularly staggered so that energy coupled to different regions of the body is absorbed by the material to thereby isolate couplers and hence sources even at close spacings. In a rectangular configuration, a non-resonant box has a planar array of serpentine or spiral resonant couplers with adjacent couplers oriented orthogonally to minimize coupling.
