Arbitrary geometry electromagnetic spatiotemporal vortices from phase velocity shearing
Jordan M. Adams, Daniel Heligman, Rajind Mendis +1
In fluids, vortices form at boundaries between flows of different velocities. Here, we show that pulsed electromagnetic waves form spatiotemporal vortices when light straddles medi…

Three-dimensional Arbitrary Electromagnetic Fields and Temporal Propagation
Jordan M. Adams, Daniel M. Heligman
We show that arbitrary 3D electromagnetic fields are transient solutions to Maxwell's equations and provide a simple equation to find how the field evolves over time. Multiple 3D f…

Laser Printing of Silver and Silver Oxide
Jordan M. Adams, Daniel Heligman, Ryan O'Dell +2
We show that direct laser writing in aqueous silver nitrate with a = 1030 nm femtosecond laser results in deposition of a mixture of silver oxide and silver, in contrast to th…
