*.cavTE

This file is the 2D cavity mode distribution by solving eigen function. The format is

M N
x(1) y(1) cavity_mode(1) cavity_mode(2) ... cavity_mode(N)
x(2) y(2) cavity_mode(1) cavity_mode(2) ... cavity_mode(N)
...
x(M) y(M) cavity_mode(1) cavity_mode(2) ... cavity_mode(N)

, where M is the total node number and N is the total number of the cavity modes.
