<P>PROBLEM TO BE SOLVED: To provide a remote point-like three-dimensional electromagnetic wave irradiation system for irradiating an arbitrary small range of the inside of a brain or the like of a human with a focus of electromagnetic wave beams by making no contact and for performing three-dimensional scan on it quickly. <P>SOLUTION: A focusing phase adjusting circuit which focuses electromagnetic waves emitted to an arbitrary point on an optical axis of a phased array antenna to focus on an arbitrary point on the optical axis (in the direction of radiation) including a central point of the phased array antenna varying the radiation direction by varying an electromagnetic wave pulse radiation time phase of each element in a plurality of electromagnetic wave radiation elements provided in the form of a matrix is provided. The electromagnetic wave is focused on a remote position which is an arbitrary distance away from the antenna. Simultaneously, the emitted electromagnetic is controlled in the vertical direction and in the lateral direction. Consequently, electromagnetic wave is focus on the arbitrary position quickly by the remote point-like three-dimensional electromagnetic wave irradiation system. <P>COPYRIGHT: (C)2009,JPO&INPIT |
