array are demonstrated. One is the coupled oscillator array using the unsymmetrical resonator circuit. The other is the injection locked coupled oscillator array using a unilateral coupling circuit. Chapter 7 is the discussion and conclusion. Further study of the SEHO and its applications are mentioned. In this dissertation, the principle of the SEHO is proposed and the basic behavior is confirmed using the MIC technology which is the basic manufacturing of the microwave integrated circuit. Compared to the conventional harmonic oscillators, the high frequency millimeter-wave signal can be easily generated without filters, mixers, and amplifiers which were required in the conventional harmonic oscillators. The proposed oscillator principle is very effective to integrate these RF circuits which have some problems for the integration. While, the semiconductor technology is steadily progressing. An InP HBT which generates hundreds of GHz millimeter-wave signal is developed. The THz signal which has been generated by optical devices will be generate by only the electronics circuit combining the semiconductor devices and the proposed principle in near future. iv
