details about perfect electric conductor(PEC)

hello,
plzzz someone help me in giving more details about perfect electric conductor(PEC) boundary conditions which is similar to PML in traditional FDTD method.

Thank you

PML is an absorbing boundary conidtion (i.e. all the power incident on it is absorbed) it is by no means related to PEC boundary conditions in which all the power is reflected.

Best regards,
adel

I Agree with Adel:
Moreover there is a very good article about PML on the website of MIT. Just search PML+MIT on google.

Other wise i will mail you
