A novel resistively loaded monocone was proposed to extend the application for electric field calibration. Electric field analysis and measurement were carried out to verify the design of the proposed monocone. As revealed by the results, the S-11 of the m ...
Far-field measurements of lightning-produced electromagnetic fields are of high importance for lightning location systems. Data from recorded lightning strokes can be, for example, used to assess the risk of lightning-induced damage in some geographical ar ...
This paper presents a preliminary work on a resonant circuit, also called AC-dipole. The resonance frequency of the circuit is changed by the mean of a variable capacitor connecting an inductor. For this purpose, a bank of switched capacitors of different ...

Miniature wind turbines, employed in wind tunnel experiments to study the interaction of turbines with turbulent boundary layers, usually suffer from poor performance with respect to their large-scale counterparts in the field. Moreover, although wakes of ...
Based on a mathematical model, simulation results show how the mechanical performances of the motor are sensitive to the prestressing force. A test bench has been developed in the laboratory for experimental measurements. The motor is driven by a two-phase ...
The milling process has been continuously optimized from many aspects: forces, velocities, stability, quality. Numerous papers have been published that report results in the domain of toolpath optimization with criteria such as raising the quality of the m ...
Nowadays digital signal processing systems used for radar applications, communication systems or RF measurement equipments, require very high sample-rates. Sometimes these sample-rates are beyond the possibilities offered by conventional ADCs. To overcome ...
This brief proposes an analytical approach to model the DC electrical behavior of extremely narrow cylindrical junctionless nanowire field-effect transistors (JL-NW-FETs). The model includes explicit expressions, taking into account the first-order perturb ...
Upward lightning happens predominantly from tall objects. The channel-base currents associated with upward negative lightning initiated from towers exhibit pulses that can be classified, based on their waveform features and on the concurrence with other pr ...
The proper characterization of lightning electric and magnetic fields is very important for a number of reasons, such as the study and design of lightning protection and the validation of return stroke models. Also, an accurate late time response of the se ...
