This thread is for engineers working on PBG

Recommended Posts

In microwave region Photonic bandgap are use and it has many advantages.

U may have come across this but many have nelglected the topic

So This thread will provide everying from basics of photonic band gap to designing devices using pbg.

I don't know how many of u are interested in new topic.

Let me start with

" Photonic Bandgap structures are periodic structures that exhibit wide bandpass and band rejection properties at microwave frequencies. By introducing dielectric rods, holes and patterns in waveguides and PCB substrates forms photonic Bandgap (PBG) structures.

" In 1987, Eli Yablonovitch proposed to carry materials with periodic structure in which electromagnetic waves could not be propagated, this, in similar way to the atomic crystals where the electronic excitations are prohibited for certain energy or frequency bands. Thus were born these concepts of Photonic Band Gap (PBG) and photonic crystals.

To be continue.........

I think no one is much intereseted in this field.

so lets close this topic

If any body want any info pm me or mail me.....

Guest sergiu

now our board is not so populated but maybe in the future some one will want to talk about BPG :) , so I've opened the topic .

no problem sergiu actually PBG it self is very unfamiliar and hidden field in microwave and optics.
