SC438 - Photonic Metamaterials

Tuesday, 15 May
12:00 - 16:00

Short Course Level: Beginner

Instructor:

Nader Engheta, University of Pennsylvania, USA

Short Course Description:

Controlling electromagnetic and optical fields and waves can be achieved via materials.  The wave-matter interaction can be engineered using structures made of materials with required parameters and structures with selected shapes, dimensions and sizes.  Recent advances in materials science and engineering, condensed matter physics, optical materials, nanoscience and nanotechnology have made it possible to tailor materials with unusual parameters and characteristics.  The field of metamaterials, along with its two-dimensional version known as metasurfaces, has seen growing interest and extensive development in recent years.  Metamaterials are engineered composite structures made of subwavelength inclusions with suitable materials and proper arrangements.  The compositions, arrangements, alignments, densities and distributions of these building blocks in host media provide a variety of degrees of freedom in the design of light-matter interaction with such structures.  Manipulation of light at the nano-, micro-, meso- and macroscales using metamaterials and metasurfaces provides rich platforms for tailoring electromagnetic waves with desired functionalities.
 
In this tutorial, we will begin with the basics of electromagnetic wave interaction with material media and structures.  Then the course will get into some of the specifics of the characteristics of metamaterials and metasurfaces including the dispersion properties, scattering mechanisms, effective-medium phenomena, and unconventional features of waves in such environments.  We will then discuss some of the specific topics in photonic metamaterials such as extreme-parameter metamaterials (i.e., epsilon-near-zero (ENZ), mu-near-zero (MNZ), and epsilon-and-mu-near-zero (EMNZ) structures) and their specialized wave-matter interactions, graphene metamaterials as a platform for ideas for one-atom-thick optical device concepts, optical metatronics (“lumped” nanocircuitry) and informatic metastuctures for photonic information processing and computing at the nanoscale, scattering engineering using metamaterials (such as cloaking), guided waves in metamaterials, and nonreciprocal metastructures.  Various features and potential applications of these topics will also be presented and discussed.  During the course, we will have interactive discussions and question-answer sessions.
