Transversily Isotropic Media

A transversely isotropic layer is flagged by stating the usual parameter line for the layer:

D

cc

cs

[L]

with c_c<0 as a flag. Here only the interface depth D has significance. The other parameters for the transversely isotropic layer should then follow in one of two ways, depending on the value of c_c:

c_c=-1:

The medium is specified as a periodic series of thin layers as per Schoenberg:

NC						Number of constituents ()
cc	cs				h	Speeds, attns., density, fraction
cc	cs				h	Speeds, attns., density, fraction

c_c = -2:

The 5 complex elastic constants and the density of the transversely isotropic medium are specified directly after the flagged layer line:

Value	Value	Units
Re(C11)	Im(C11)	Pa
Re(C13)	Im(C13)	Pa
Re(C33)	Im(C33)	Pa
Re(C44)	Im(C44)	Pa
Re(C66)	Im(C66)	Pa
		g/cm3

If option Z was specified in the option line, then a slowness diagram is produced for each transversely isotropic layer.
