any thesis about electromagnetic bandgap,high impedance magnetic surface,frequency selective surface,master or doctoral thesis,i will be thanks for help me in my study of these issue in my work of high directive antenna
or thus its name

Working on it 
What exactly are you interested in? I have collected a vast amount of articles during my master research (which I am working on), so maybe I could direct you to something special.
My research focusses mainly on artificial magnetic ground planes for application in zero-wavelength salisbury absorbers

Dear all,...
Help me in my final project.
i made microstrip antenna and concerned about electromagnetic band gap with defected ground structure (DGS) where i create slot at the ground metal form my antenna.
but i m very poor about theory of EBG and DGS. if u dont mind can u give some advice for my project..
i m working with microwave studio for simulation.
thanks in advance

This one could be a good starter:
http://ceta.mit.edu/PIER/pier61c/02.0601171.SK.Tae.L.pdf
Sohn et al investigate 4 types of AMC's for low profile antenna applications: a sievenpiper surface, uniplanar EBG, peano fractal and hilbert fractal curves.
Basically, these all act as a planar resonant LC circuit and therefore reflect the E field in phase. This way the antenna could be close to the surface (instead of 1/4 λ for a PEC)
For further basic info, there's an awful lot of articles about sievenpiper surfaces (starting in 1999: http://scholar.google.nl/scholar?hl=nl&lr=&cluster=15442605938087014411), J McVay, N Engheta and A Hoorfar did a lot on peano and hilbert fractal curve AMC's (for instance: http://scholar.google.nl/scholar?hl=nl&lr=&cluster=12872121660587165093)
I myself am currently working on the application of such AMC's to replace the PEC and 1/4 λ spacer in salisbury screen absorbers, doing simulations in HFSS and FEKO.
Can't get to you through e-mail, since that's all blocked from within the company (defence)
I could mail in weekends, but then I won't have all info with me however. Subject is completely unclassified, so I am allowed to tell you anything, but there are limited options to do so. If you want, you can call me by old school telephone however

| hi heviraf. I´ve been working with EBG´s to mitigate simultaneous switching noise and recently I´m studying DGS to do the same. I´ve designed a mushroom-like EBG in a double layer PCB. I´d like to know more about your project to try to help you. Greetings
