Digital manufacturing, or 3D printing, is revolutionizing manufacturing. It offers the ability to place precise amounts of different materials throughout all three dimensions, enabling us to produce previously unimaginable structures in a single seamless process step. All of this promises a very 3D future for electromagnetics and photonics, which remain primarily planar technologies. This webinar, hosted by the OSA Photonic Metamaterials Technical Group, will discuss the pioneering steps of the EM Lab to explore new concepts in metamaterials and photonic crystals that fully exploit the third dimension.

Dr. Raymond Rumpf, founder of the EM Lab, will be discussing their algorithm to generate spatially-variant lattices. This algorithm can bend, twist, and otherwise spatially vary a periodic structure without deforming the unit cells. This gives designers of metamaterials and photonic crystals new and profound degrees of freedom. The algorithm can be used to put planar periodic structures onto curved surfaces while maintaining the size, shape, and spacing of the elements in the array. Using this algorithm, the EM Lab discovered several new mechanisms for controlling light and electromagnetic fields. Spatially-variant anisotropic metamaterials were discovered to be able to sculpt the near-field around components and are currently being studied to reduce the coupling and interference experienced between components placed in close proximity. The EM Lab has developed a new class of spatially-variant photonic crystals that provide new ways to control light and circumvent the limitations imposed by refraction, which will also be discussed during the webinar.

What You Will Learn:

  • New techniques to sculpt electromagnetic fields and control photons
  • New concepts in metamaterials and photonics crystals enabled by 3D printing

Who Should Attend:

  • Those interested in new concepts in metamaterials and photonic crystals enabled by digital manufacturing
