Looking for info about RFID physics

Hi everybody
I am working on RFID for my university thesis. and I want to know more about RFID physics and structure. can any body help me. I approciate him.

What frequency?
You can find equations for coil design for 125kHz & 13.56MHz on the Microchip website:

For details on RFID principles, check "RFID handbook" - Klaus Finkenzeller:
www.rfidhandbook.de/
and "Smartcard handbook" - oriented more on software.

You can find standard drafts on http://wg8.de/ .

This is for LW - HF RFID, I worked only with RFID on 13.56MHz.
RFID on microwave is more interesting and complex...

thanks alot for your help.
I am working on 13.56MHZ for library management.
