In layman's terms, I was modelling how light and electric currents behave in the above-mentioned compound materials. Frankly, I prefer this version over 'glamorous to the max' representation it would get via MIT-grade finance and marketing departments. You know, like this:
A breakthrough in metamaterials research developed by a brilliant undergraduate from a prestigious university which will bring the following very speculative technologies of which you'll never hear about again to your home within the next few years. "I bet that it, like, totes improves keggers!" remarked our science correspondent from Arizona State U.
On a more serious note, undergrad level research is rarely fascinating. It's mostly about showing that you can conduct any (reasonably independent) research at all and won't break any equipment that has real value. In comparison to most MSc topics form this year's lists it's almost a night and day situation.
