(Color online) Intensity transmission coefficients for a four-layer medium for the case when the third layer is 3 mm thick. The transmission coefficients are shown for a plane wave incident on the medium at 10° when the first layer is assumed to be an elastic solid (green solid line) and a fluid (red dashed line), and when a plane wave is incident on the medium at 30° when the first layer is assumed to be an elastic solid (black dashed line) and a fluid (blue dotted line). Note that Tf denotes the transmission coefficients when the first layer is assumed to be a fluid and Ts denotes the transmission coefficient when the first layer is assumed to be an elastic solid.
