d _i (i=1)=r ₁ ,

_{d i (i> 1) =} r i -r j,

Among them, r _n represents the radius of the nth (n = 1, 2, 3,..., N) Fresnel zone; λ = c/f represents the wavelength of the sound wave, c represents the speed of sound, and f represents the center frequency of the sound wave; F represents a predetermined focal length; d _{i (i} = 1) represents a radius of the center circular hole; d _{i (i>} 1) denotes the width of the slit other than or in addition to the central circular ring; R & lt comprising _i represents the i-th round The radius of the smallest Fresnel zone of the ring or slit, r _j represents the radius of the largest Fresnel zone within the aforementioned smallest Fresnel zone that is smaller than the aforementioned smallest Fresnel zone.
