Method for the Generation of arbitrary uniform fields based on angular spectral domain and time reversal technique

Existing uniform fields are usually based on the special arrangement of array antenna. The generated by flat-top beam shaping in angular far-field area or point focusing near-field directly subject to configuration and cannot be flexibly controlled. This paper presents a field generation method combination spectral domain improved time reversal techniques. is not limited arrangement. It can generate specified size, shape deflection angle at arbitrary location, including near area, same In this paper, reason why theoretically explained. Secondly, ability fixed multiple validated numerically. Finally, technique signal amplitude reciprocal weighting introduced. problem deterioration flatness caused decay phase delay during solved through technology. results show that quality synthesized related main lobe sidelobe information its corresponding spectrum envelope, generating must contain least half information. control position, one-dimensional two-dimensional fields, which provides new approach for fields.
