PLOTRTH produces plots of the plane wave reflection coefficient
as a function of angle ( R(THETA) ). Reflection loss defined
as -20 log10 ( R ) may also be plotted. An Internal Reflection
Coefficient file computed by * BOUNCE*
provides the input.

THMIN, THMAX, THINC, THAXL (cm) 0.0 15.0 5.0 / ! RMIN, RMAX, RINC, RAXL (cm) (1) - OPTIONS Syntax: OPTION Description: OPTION(1:1): Reflection coef. or reflection loss. 'L' Linear scale (reflection coef.) 'D' dB (reflection loss.) (2) - Reference wave speed Syntax: C0 Description: C0: Sound speed in the halfspace. The reflection coefficient depends on the sound speed and density of the medium from which the wave is incident. The density is assumed unity. (3) - ANGLE AXIS INFO Syntax: THMIN THMAX NTH THINC THAXL Description: THMIN: First angle (degrees). THMAX: Last angle (degrees). THINC: Angular interval for tick marks (degrees). THAXL: Angle axis length (cm). (4) - REFLECTION LOSS AXIS INFO Syntax: RMIN RMAX RINC RAXL Description: RMIN: R minimum (dB). RMAX: R maximum (dB). RINC: R interval for tick marks (dB). RAXL: R axis length (cm). If you set RMIN=RMAX then the curve is autoscaled.
