Research

Photonic bandgap design.

This is an ongoing project in collaboration with Francis Ndi, a graduate student in Physics at Lehigh University. Phung Nguyen and Steve Mokris have contributed to this project as Anderson Scholars over the summer of 2003. Phung Nguyen continued his involvement in this project over the summer of 2004 as an Anderson Scholar. The state of this project is described in a recent write-up, as well as in Phung and Steve's poster.

I invite further undergraduate participation to help answer open questions in both the theoretical and the numerical aspects of the project. The project combines elegant theoretical principles and optimized computational techniques, and applies them to photonics - a currently 'hot' area.

Scattering of waves off rough surfaces.

This is a U.S. NSF funded project in collaboration with Dr. Daniel Nkemzi at the University of Buea, Cameroon. A recent publication presents the current status of this project.

Narayan Choudury, a Denison undergraduate and participant in this project, traveled to Cameroon in August 2005. Here are some pictures from his trip: of Mt. Cameroon from Buea, of the Atlantic at Limbe, and of our research group.

Scattering of light at photonic crystal interfaces

This is a Research Corporation funded project that will explore, analytically and numerically, the scattering of light at the interface between photonic crystals using Pade approximants. This is closely related to both the projects described above. Steve Mokris has been involved in this project over the summer of 2004, and Narayan Choudury, the summer of 2005. Students interested in collaborating on this project are encouraged to contact me.

Quantum information.

There are numerous sub-topics of interest to me. One of them - quantum clock-synchronization - has resulted in a recent publication. Cameron Biganek has been working on a density-matrix based quantum computer simulator that is scheduled to go online soon. Interested students are encouraged to contact me.
