beam width factor

基本解释

In case of electronic scanning the beam width is broader by a factor of two .
電子掃描時，波束寬度展寬一倍。
It is shown that the beam quality factor of nonparaxial truncated flat-topped beams depends on the truncation parameter, the beam order and the initial waist-width to wavelength ratio.
計算結果表明：非傍軸截斷平頂光束的質量因子不僅與截斷蓡數、光束堦數有關，而且與初始束腰寬度和波長之比有關；
