# TM mode bend loss

#1

Dear All,

I have been trying to simulate the bending loss for a TM mode. I am not sure if the method is correct since the results are not convincing for me because I get the T_forward larger than the T_total in the expansion monitor.

I calculate the bending loss by dividing the T_forward by the input monitor transmission.

Please find attached the file I used to test the bend_loss.
