摘要:For quite a few years, optical antennas and resonant structures have been the focus of several well-established fields that nonetheless are pushing the boundaries of science and technology. Between the 19th century foundations of electromagnetism and the 21st...

摘要:Fabrication of infrared and optical antennas requires high-resolution lithography so that thin films of the required materials can be deposited and patterned onto a suitable substrate. Resonant structures, including multilayer arrangements, are also made with nanofabrication...

摘要:These days, when computational power and resources are widely available, it is commonplace to rely on numerical tools that have demonstrated their capabilities to simulate physical phenomena involving electromagnetic radiation and its interaction with materials. However, we shoul...

摘要:Infrared antennas and resonant structures take advantage of the successful designs in the radioelectric and microwave spectra. A quite simple and naïve approach would be to consider the geometry and shape of those designs and transfer them into the optical regime with simple...

摘要:Classical electromagnetism and photonics share a common foundation. Light propagation and interaction, even at the nanoscale, is driven by Maxwell’s equations and macroscopic parameterization of materials through their optical and electromagnetic properties [Jackson, 1998].

摘要:Optical or infrared antennas are devices that receive optical radiation and transform it into a current within the resonant structure. This high-frequency current is transduced by a given mechanism to a change in voltage or current that is read by external electronics. From this ...

摘要:When dealing with light and optics, it is commonplace to constrain our understanding to the visible range of the electromagnetic spectrum, i.e., the narrow interval where the human eye is able to respond. However, this anthropomorphic definition of optics is too narrow. On b...

摘要:The general class of devices called resonant optics is periodic or quasi-periodic and consists of metallic unit cells arranged in a 2D array on a dielectric substrate. We generally used 2D structures in our investigations, with multilayer structures used on occasion. Some embodim...
