Suggest the best book for Emi filter design and selection

Hello Sathishkumar,
I wish there was just one book for EMI, it would make things easier.
However EMI presents itself in many ways. It is not just the power supply.

Since you posted in the Power Forum I will start with that topic.
For power supply design please see:
Power Supply Design Seminars.
