We propose a novel technique for building YIG film-based resonators and waveguides for high power operating microwave devices. Our approach is based on the effect of total internal reflection (TIR) at the interface between the non-metalized and metalized regions of YIG film, which take place for forward volume magnetostatic spin waves in perpendicularly magnetized YIG films. Prototype resonators and waveguides were designed, fabricated, and tested. The obtained experimental data demonstrate high quality factor of 50 dB and a high power operation up to +15 dBm in the frequency range from 1.8 GHz to 5.1 GHz. Application of such resonators and waveguides in electrically tunable microwave oscillators promises an extremely low phase noises about - 135 dB/Hz at 10 kHz offset.
