| Outline of Final Research Achievements |
The purpose of this project is to generate diffraction free beam in millimeter-wave band by the simulation. Existence of the diffraction free beam has been already proved theoretically. The proposed generation system for diffraction free beam consists of an antenna, a conducting plate with an annular ring slit, a thin lens and wave absorbers which are used to suppress the diffraction wave at the edges of the conducting plate and the thin lens. In the proposed antenna and the designed wave absorbers, the favorable results were obtained. However, the sufficiently large thin lens couldn’t be designed because of the limitation of the RAM of the computer for the simulation. Therefore, the diffraction wave at the edge of the thin lens was generated and it prevented the generation of the diffraction free beam.
