Meep isn’t just the sounds of Road Runner and Beaker the Muppet. Meep is his package of software originally developed by a physicist at MIT as his custom code written in C++ in the early 2000s to facilitate his academic research on photonic crystals. Released as open source in 2006. After nearly 20 years of continuous development and growth, with the contributions of over 40 developers, Meep is now widely used in the photonics community to study nano-optics and other electromagnetic systems.

To bring together Meep users, the first MeepCon user and developer conference was held at MIT from July 27th to 29th, both virtually and in person. Participants from around the world develop tutorials, technical talks, and applications for electromagnetic modeling.

MeepCon co-organizer MIT said: Professor Stephen Johnson. “Hosting MeepCon was a great opportunity to interact live (both face-to-face and remotely) with people who are using our software in exciting applications around the world. Innovative research at technical talks and tutorials, and we want to continue this tradition.”

Johnson is a professor of applied mathematics and physics working in the field of nanophotonics, addressing many aspects of theory, design, and computational modeling of classical and quantum nanophotonic devices.

Other MeepCon organizers were Ardavan Oskooi SM ’08, ScD ’10 from Google and Alec Hammond from Georgia Tech. Oskooi and Johnson maintain the Meep repository on GitHub. Georgia Tech professor Stephen Ralph, who is collaborating with Johnson on using Meep for inverse design and topology optimization in silicon photonics, also brought a team of students to the conference to participate in the development of his new Meep feature. rice field.

Meep, an acronym for MIT Electromagnetic Equation Propagation, is an open-source software package for electromagnetic simulation with finite-difference time-domain methods, spanning a wide range of physical materials and applications. It is used in both teaching and research at MIT and other institutions.

Thanks to Meep, researchers have made advances in optical and wireless technologies such as photovoltaics, ultra-thin lenses, wireless power, and radar. Such electromagnetic modeling uses computer simulations to understand how electromagnetic fields interact with physical objects and the environment, to calculate the performance of everything from nanoscale lasers to radio antennas, and to measure how light travels through complex structures. It reveals complex mathematical phenomena that occur when

Mo Chen, a fourth-year graduate mathematics student, calls Meep an “essential tool” for the study, analysis, and design of photonic structures. He is a member of Johnson’s nanostructural and computational group, and Oskoy is also counted as an alumni.

“MeepCon was a great experience,” says Chen, who ran a tutorial showing how to use Meep’s adjoint solver for the inverse design of a metasurface lens. “It has been a great pleasure meeting the rest of the community through MeepCon and I look forward to the possibility of collaborating with them in the future.”
