Abstract Pulsar radio emission may be generated in pair discharges that fill the pulsar magnetosphere with plasma as an accelerating electric field is screened by freshly created pairs. In this Letter, we develop a simplified analytic theory for screening of these and use it to estimate total luminosity spectrum. The discharge has three stages. First, first time starts oscillate. Next, nonlinea...

This work presents the development of an inductive current sensor for measuring pulsating corona discharges observed under high background electric field. Laboratory and field experiments in different setups are used to corroborate discharge features. The first location is on roof a regular building, second flat area. Due enhancement E-field caused by lightning strikes vicinity grounded rod wit...

The lightning discharges are one of the main causes of interruptions of medium voltage overhead distribution lines, being the reason of great concern for the utility companies. Its destructive effects frequently extends to equipments and connected installations, with the possibility to cause personal injuries and material damages, beyond economic losses, due to out of income and the possibility...

We consider the distribution of an electric field in YBa2Cu3O7−x (YBCO)-coated conductors for a situation in which the DC transport current is forced into the copper stabilizer due to a weak link—a section of the superconducting film with a critical current less than the transport current. The electric field in the metal substrate is also discussed. The results are compared with recent experime...

Modeling the electric field and images in electric fish contributes to a better understanding of the pre-receptor conditioning of electric images. Although the boundary element method has been very successful for calculating images and fields, complex electric organ discharges pose a challenge for active electroreception modeling. We have previously developed a direct method for calculating ele...

The electric sense of elasmobranch fishes (sharks and rays) is an important sensory modality known to mediate the detection of bioelectric stimuli. Although the best known function for the use of the elasmobranch electric sense is prey detection, relatively few studies have investigated other possible biological functions. Here, we review recent studies that demonstrate the elasmobranch electro...

Sprite discharges above thunderclouds at altitudes of 40–90 km (refs 1–5) are usually created by a strong positive cloud-to-ground lightning flash6. Sometimes these sprite discharges emerge from a visible halo5,7–9, and during the first stage they always propagate downwards and branch on their way5,7,9–11. Modelling efforts have been restricted to conditions of non-ionized air of constant densi...
