Acoustic Transfer Matrix dialog box

Modeling Object
Name	Sets the name of the acoustic transfer matrix.
Label	Sets the label for the acoustic transfer matrix.
Properties
Description	Sets a description for the acoustic transfer matrix.
	The transfer matrix formulation is given by:where:P1 = Inlet pressureP2 = Outlet pressureV1= Inlet velocityV2 = Outlet velocityYou can define the following transfer matrix parameters:T11 — UnitlessT12 — Unit is pressure per velocityT21 — Unit is velocity per pressureT22 — UnitlessFor more information, see Boundary conditions overview (FEM acoustics).
Coefficients
T11/T12/T21/T22	Specifies how the acoustic transfer matrix is defined.Note: T11 and T22 are unitless.
Real	Available when T11/T12/T21/T22 is set to Real/Imaginary.Sets the real component value of the acoustic transfer matrix coefficient.
Imaginary	Available when T11/T12/T21/T22 is set to Real/Imaginary.Sets the imaginary component value of the acoustic transfer matrix coefficient.
Magnitude	Available when T11/T12/T21/T22 is set to Magnitude/Phase.Sets the magnitude value of the acoustic transfer matrix coefficient.
Phase	Available when T11/T12/T21/T22 is set to Magnitude/Phase.Sets the phase angle value of the acoustic transfer matrix coefficient.
Specify Field	Available when T11/T12/T21/T22 is set to Field.Specifies the frequency dependent complex field values.Options include:Select Existing Field from List opens the Fields dialog box, where you can select a field.A field can define a magnitude that varies with independent variables such as frequency, temperature, or time. For more information about fields, see Fields.Formula Constructor opens the Formula Field dialog box, where you can define a formula to construct a field.For more information, see Define a boundary condition using a formula field.Table Constructor opens the Table Field dialog box, where you can define tabular data to construct a field.For more information, see Define a boundary condition using a table field and Define a material property using a table field.Plot (XY) plots the field as an XY graph.For more information, see Graph overview.Overlay (XY) overlays a plot on an existing plot. You can overlay up to 50 plots.For more information, see Overlay plots.Scale Factor — Sets the scaling of values present in the Field.
