Description: This tutorial focuses on how metasurfaces enable the redesign of optical components into novel thin and planar diffractive optical elements, that overcome the limitations of Fresnel and refractive optics, promising a major reduction in footprint and system complexity as well as the introduction of new optical functions. The planarity of flat optics will lead to the unification of semiconductor manufacturing and lens making, where the planar technology to manufacture computer chips will be adapted to produce CMOS-compatible metasurface-based optical components, ranging from metalenses to novel multifunctional phase plates.

Description: In this tutorial, I will present an overview of some of the fundamental principles and unique features of wave interaction with structures with effective refractive index near zero, which include epsilon-near-zero (ENZ), mu-near-zero (MNZ), epsilon-and-mu-near-zero (EMNZ) and Dirac-cone photonic media. I will then discuss some of the applications of near-zero-index metamaterials in photonics and microwave technologies. Possible future directions of research in this field will also be forecasted.

Tutorial length: 1 hour

Description: Almost twenty years ago, some of the earliest research into metamaterials and their applications was funded by DARPA.  The field has grown enormously since, and DARPA still supports fundamental research into improving our understanding and modeling of these engineered materials. This talk will provide the background and context for research of current interests. These include the study of new material properties, including bianisotropy and nonlinearity, advancing flat optics, and developing nonreciprocal and tunable components, all of which may impact imaging and remote sensing capabilities.

Dr. Rachel Won, Nature Photonics, UK

Tutorial length: 1 hour

Description: In this tutorial, Rachel will talk you through the detailed information and guidelines on scientific paper preparation and submission. Guidelines and tips for writing an abstract and a paper will be provided. Submission, editorial and peer-review processes will be discussed. At the end of the tutorial, you will walk away knowing how to write an informative cover letter, an outstanding abstract and a comprehensive scientific paper. You will also get to know where to submit your papers to, what editors seek, how your papers are reviewed and how to make an appeal.

Description: There is an aspect of Electromagnetics that has been somewhat overlooked.  Common everyday objects can act as electromagnetic resonators.  Indeed ordinary objects have a series of resonant frequencies extending from radio waves up to optical frequencies.  These resonant modes can be modeled as LC circuits.  Thus every object that we encounter is an LC resonator.  Since LC circuits support ac currents, and since ac currents imply electron acceleration, they inherently radiate into the far-field.  Therefore ordinary objects that we come across, in our daily lives, can act as electromagnetic antennas.  This means that ordinary object have a Q-factor and a radiation Q-factor for each resonant mode.The lowest frequency resonance is especially characteristic of the object geometry, but there is an entire spectrum of higher frequencies to work with, a spectral fingerprint for everyday objects.  Many of the properties that have been attributed to plasmonic resonances are actually universal, and they arise already in ordinary electromagnetics.In communications technology, the antenna application is the most important.  The antennas in cellphones, carried by almost everyone on the planet, are examples of multi-frequency resonant objects, enabling wireless connectivity.
