An attractive alternative treatment for malignant tumors that are refractive to conventional therapies, such as surgery, radiation, and chemotherapy, is electrical-pulse-mediated drug delivery. Electric field distribution of tissue/tumor is important for effective treatment of tissues. This paper deals with the electric field distribution study of a tissue model using MAXWELL 3D Simulator. Our ...

Direct amplitude and phase shaping of mid-infrared femtosecond pulses is realized with a calomel-based acousto-optic programmable dispersive filter transparent between 0.4 and 20 μm. The shaped pulse electric field is fully characterized with high accuracy, using chirped-pulse upconversion and time-encoded arrangement spectral phase interferometry for direct electric field reconstruction techni...

Electrochemical reactions, especially those involving the electrode material, are considered one of the challenges facing the commercialization of the process of food preservation using pulsed electric fields. These undesired reactions lead to the migration of electrode material components into the food under treatment affecting food quality and taste, electric field distribution, and electrode...

Irreversible electroporation (IRE) ablation uses brief electric pulses to kill a volume of tissue without damaging the structures contraindicated for surgical resection or thermal ablation, including blood vessels and ureters. IRE offers a targeted nephron-sparing approach for treating kidney tumors, but the relevant organ-specific electrical properties and cellular susceptibility to IRE electr...

Chalcogenide superlattice (SL) phase-change memory materials are leading candidates for non-volatile, energy-efficient electric memory where the electric conductance switching is caused by the atom repositioning in the constituent layers. Here, we study the time evolution of the electric conductance in [(GeTe)2/(Sb2Te3)1]4 SLs upon the application of an external pulsed electric field by analysi...

Pulsed electric field (PEF) is commonly understood as a fast, non-thermal, and highly effective method for extraction of intracellular compounds. This treatment involves discharge of high voltage electric pulses of a few microseconds into the food product which is placed or passed between two electrodes (Angersbach et al., 2000). Results of experimental investigation of the electric breakage of...

Bilateral cochlear implant (CI) listeners currently use stimulation strategies which encode interaural time differences (ITD) in the temporal envelope but which do not transmit ITD in the fine structure, due to the constant phase in the electric pulse train. To determine the utility of encoding ITD in the fine structure, ITD-based lateralization was investigated with four CI listeners and four ...

Electric field pulse bursts generated by lightning flashes are considered as sources of high radio frequencies. In this study, an analysis of pulse bursts in electric field records of 30 negative cloud to ground lightning flashes recorded in the southern coastal area of Sri Lanka is presented. Sixty-four percent (64%) of pulse bursts are typical chaotic pulse trains (CPT). Twenty-four percent (...
