Pacing and Clinical Electrophysiology, Volume 49, Issue 1, Page 5-14, January 2026.ABSTRACT The goal of a cardiac pulsed field ablation (PFA) system is to provide safe, effective, and usable therapy for the treatment of cardiac arrhythmias. Achieving this goal is a complex exercise in system design, requiring optimization of catheter, waveform, and dosing. This optimization is often iterative, as myriad design factors are balanced to

Computer Simulations of Charged Colloids in Alternating Electric Fields
, 2013 We briefly review recent theoretical and simulation studies of charged colloidal dispersions in alternating electric fields (AC fields). The response of single colloid to an external field can be characterized by a complex polarizability, which describes

Development of a single cell spherical shell model for an investigation of electrical properties with a computing program [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2005 A spherical double shell model (SDM) for a single cell has been developed, using Laplace’s equation in spherical coordinates and boundary conditions. Electric field intensities and dielectric constants of each region inside and outside of the cell have ...

Dielectric behavior of oblate spheroidal particles: Application to erythrocytes suspensions
, 2002 We have investigated the effect of particle shape on the eletrorotation (ER) spectrum of living cells suspensions. In particular, we consider coated oblate spheroidal particles and present a theoretical study of ER based on the spectral representation ...

Electrothermal flow in Dielectrophoresis of Single-Walled Carbon Nanotubes
, 2007 We theoretically investigate the impact of the electrothermal flow on the dielectrophoretic separation of single-walled carbon nanotubes (SWNT). The electrothermal flow is observed to control the motions of semiconducting SWNTs in a sizeable domain near ...
