Abstract

In this paper, a millimeter-wave Y-shaped circulator based on magneto photonic crystals is demonstrated. The triangular lattice photonic crystal with Y-shaped line defect waveguide is constructed by Al2O3 ceramic posts. The magneto-optical cavity resonator in the junction of Y-shaped waveguide consists of two cylindrical ferrites and two triangular metal pedestals. The transmission characteristics of the circulator experimented under the external magnetic bias H0 = 300 Gs. In working frequency range 24∼28 GHz the isolation of circulator is better than 20 dB, and the best insertion loss is as low as 0.2 dB. The experimented results are well agreed with the simulation results.
