Metamaterial for gain enhancement

Hello,

I have this article in the attachment. Does anybody know how to compute "a" and "r" of lattice on the second page? From which formulas specifically did they get dimensions specified on the 5th page (6.5mm inner and 7.6 outer). How would the dimensions change for 10 GHz.

The article is free and is also accessible from:

Also, does anybody know where to find simulation of such things in HFSS?


Many thanks in advance.

Hi all
I need to design a super lens for gain increasing of printed antenna
albiet my project is "gain enhancement of printed antenna using metamaterials"
I need to your help for guidenece in design and simulation.
HELP ME!
Thanks very much.
