ultrasonic optable → tableimport fullseye as fs; fs.ledger.acoustic_interface_coefficients(stack) (実装を直接呼ぶなら import ultrasound; ultrasound.acoustic_interface_coefficients(stack)、台帳から引くなら opsacoustics.get("acoustic_interface_coefficients"))Pressure reflection/transmission at every interface of a stack, energy check R^2 + (Z1/Z2) T^2 = 1, and the phase-inversion flag Z2 < Z1 (table).
R = (Z2 − Z1)/(Z2 + Z1)(圧力)、T = 2 Z2/(Z1 + Z2)。R < 0 ⇔ Z2 < Z1
(エコーの反転)。半無限どうしの界面の値で、薄い層の多重反射は入らない
