ConcertedAmplifzcation is defined as "Induced non-linear phenomena in the proceeding reaction fields by external energy". Research on Advanced Materials Processing on the Basis of Concerted Amplification started in 1998 by Special Coordination Funds of the Science and Technology Agency of the Japanese Government. Seventeen organizations take part in the research program with various techniques of external energy, such as magnetic field, electric field, plasma, ultrasonic wave, and mechanical energy. Some distinguished results obtained through the collaborative works are described.
