The lesser electric ray, Narcine brasiliensis, is a small, demersal ray capable of generating electricity through its main and accessory electric organs. Although closely related to the large piscivorous torpedo rays, it differs in size, habitat, and prey. Based on these differences, we hypothesized that the main electric organs are used for predator defense rather than feeding and that the acc...
In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...

The collision frequency should definitely be taken into account in high pressure discharges. In this work by using forth order of Rung Kuta method, and two-fluid model, temperature dependence of the characteristics of a collisional DC plasma sheath, such as electric field, electric potential, ion and electron number density, and ion velocity, has been studied. It will be shown in the constant c...
We investigated the possibility to trigger real-scale lightning using ionized filaments generated by ultrashort laser pulses in the atmosphere. Under conditions of high electric field during two thunderstorms, we observed a statistically significant number of electric events synchronized with the laser pulses, at the location of the filaments. This observation suggests that corona discharges ma...

Electric fields of repetitively pulsed nanosecond discharges have been measured from electric-field induced Raman scattering by hydrogen molecules. Especially the temporal evolution of the electric field spatial distribution was recorded. With a high-speed optical emission intensity analysis, it has been found that most ionization events take place within a very short period during an ionizatio...
We present an adaptive animation method for electrical discharges. Electric discharges can be simulated using the dielectric breakdown model. Regular discretization of the governing Laplace equation leads to huge equation systems, and the computational cost of solving the equations quickly becomes prohibitive at high resolutions, especially for simulations in 3D. In contrast, our method discret...
A physical picture and quantitative two-dimensional electromagnetic modeling of mesospheric electric field transients produced by cloud-to-ground (CG) lightning discharges with short duration currents (<0.5 ms) are presented. The range of applicability of existing quasi-electrostatic models of sprites and the physical conditions under which relatively weak CG lightning discharges (thundercloud ...
