acoustic_interface_coefficients — ACOUSTICS ultrasonic op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.acoustic_interface_coefficients(stack) (to call the implementation directly, import ultrasound; ultrasound.acoustic_interface_coefficients(stack); from the registry, opsacoustics.get("acoustic_interface_coefficients"))

Usage

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).

> The detailed description below is the original text — the summary and the headings are translated.

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(それは pulse_echo_ascan)。返り: names z1 z2 R T energy inverted t_interfaces depth。Raises ValueError: 印(kind='acoustic_stack')の無い table。
