Deep Learning for the modeling and design of artificial electromagnetic materials
<p>Artificial electromagnetic materials (AEMs) are materials that exhibit unusual electromagnetic properties. With sub-wavelength, periodic structures, AEMs can achieve incredible abilities to manipulate light, like the cloaking effect of the “invisibility cloak” in the Harry Potter movie. Apart …

Anomalous Nature Of Metamaterial Inclusion and Compact Metamaterial-Inspired Antennas Model For Wireless Communication Systems. A Study of Anomalous Comportment of Small Metamaterial Inclusions and their Effects when Placed in the Vicinity of Antennas, and Investigation of Different Aspects of Metamaterial-Inspired Small Antenna Models
Metamaterials are humanly engineered artificial electromagnetic materials which produce electromagnetic properties that are unusual, yet can be observed readily in nature. These unconventional properties are not a result of the material composition but rather of the structure formed. The objective …

Design, fabrication, testing, and application of a sub-wavelength microwave lens
… with lenses made from conventional dielectric materials. Subwavelength focusing is attractive for a variety of applications, including medicine, optics, and mining. By creating a focal spot smaller than the traditional diffraction-limited size, higher power density can be achieved in the focal …

On numerical methods for direct and inverse problems in electromagnetism
… to the study of processes in the propagation of electromagnetic fields. We do not aim at one particular problem, actually very different kinds of topics are analyzed here. We deal with direct problems as well as with inverse ones, low frequency electromagnetism is discussed and consequently the …

On the parallels between the Maxwell and Dirac equations
… these electronic fields closely parallel their electromagnetic counterparts. We also make a discussion on wave components we may measure if the matter wave is actually measurable. Likewise, we reformulate Maxwell’s equations into an \emph{exact} form of the Dirac equation, which we term the …
