Introduction of Research activities:
The research focuses on developing fast and efficient algorithms for computational electromagnetics. The applications of such algorithms range from wireless communication, antenna design, imaging processing for non-destructive evaluation, radar scattering, high speed circuit design and analysis.

DLX cluster (previously BCX) has been used for the following projects:

A Multilevel Fast Multipole Algorithm for Electromagnetic Simulation of Microwave Structures Using Mixed Mesh and Hybrid Integral Equations (NSF):

Descriptoin: To develop integral equation solver for modeling of complex high speed circuit structures with focus on printed circuit modeling.

Research Participants:

PI: Caicheng Lu,
Zhiyong Zeng, Chong Luo, Mouri Lee (RA).

Full-Wave Modeling Using Curvilinear Surface and Volume Meshes for the Calculation of Radar Scattering from Material Coated Targets (ONR):

Description: To develop fast electromagnetic computation software for scattering calculation of dielectric material and conducting objects.

Research Participants:

PI: Caicheng Lu,
Chun Yu (Post-Doc), Chong Luo (RA)

Advanced Electromagnetic Modeling Using Nystrom Method and Hybrid Integral Equations (DARPA):

Description: To develop highly accurate and highly robust algorithm for calculating of scattering by dielectric material objects.

Research Participants:

PI: Stephen Gedney, Co-PI: Caicheng Lu

Development of the novel single-mode electromagnetic resonance technology for rapid and uniform warming of cryopreserved living cells and organs (KSEF)

Description: This project has two parts, experimental and numerical modeling. The numerical modeling part has used UK's HPC system to generate data for analysis of microwave heating of cryoprotected material.

Research Participants:

PI: Caicheng Lu,
Xu Han, and David Luo (RA)
Other projects (for which I am a participant) will be reported by Dr. Stephen Gedney.

Software used:

We primarily focus on testing and evaluation of the algorithms , and hence the software are basically those we developed. Of course, we will use the various compiling software and the related libaries (BLAS, LAPACK, and ScaLAPACK, for example).
