本文提出了一種利用混合型幾何相位超原子(HGPM)對中兩個模式轉換路徑之間的干涉來連續調節聲波幅度的策略,並通過仿真和實驗驗證了該策略的可行性。
Statistik
HGPM對的旋轉角度與透射聲波幅度之間呈餘弦函數關係。
研究人員實現了接近100%的幅度調製深度。
一階和二階HGPM對的最佳工作頻率分別為1238 Hz和1269 Hz。

"In this work, we provide a solution to continuously control the amplitude of the acoustic wave by taking advantage of the interference of two mode-conversion paths."
"Results of the simulations and experiment measurements agree well with our theory, where a continuous modulation of the amplitude of the transmitted acoustic wave with a 100% modulation depth is achieved."
