Where Can I Find Resources for My Photonics Band Gaps Final Project?

I need some advice for where to start my project which is about Photonics band gaps. I need to write a 10 pages paper on this subject. I am sure I will be asked a lot about the subject which won't even be in my paper so I need to learn about it as much as I can. But,unfortunatelly I don't know much about Photonics. Do you know any good webpages that gives information about this ?

thanks

Personally I'd start in the library and find a good textbook with some background about photonics in it then perhaps a couple of recent papers on the subject. Its important you get a grounding even if it is the most basic in the subject area first from an introductory text. It is also important for the project since you'll have to show usually in the opening sections what the physical overview of the subject is.

The internet sources are perhaps best for seeing where recent research is heading in that particular field and I wouldn't use it for any more research than that.

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
