Presentation / Conference Contribution
Ramli, K., Abd-Alhameed, R., See, C., Zhou, D., Elkhazmi, E., & Excell, P. (2009, December). Precise computation of the induced fields inside biological cell tissue using floquet boundary and subgridding quasi-static FDTD method. Presented at 2009 Asia Pacific Microwave Conference - (APMC 2009), Singapore, Singapore

This paper demonstrates the detailed electromagnetic modelling of biological cell structures by using modified subgridding FDTD techniques. This is done by incorporating a quasi-static FDTD solution, Floquet periodic boundary conditions and modified...
