This article introduces a novel version for implementing current-mode precision full-wave rectifier and class B push-pull current amplifier. The features of the proposed circuits are that: it can rectify and amplify current signal with controllable output magnitude via an input bias current: the output current save ideally free from temperature variation. In addition, direction of the output cu...

it is well-known that dam-reservoir interaction has significant effects on the response of dams to the earthquakes. this phenomenon should be considered more exactly in the seismic design of dams with a rational and reliable dynamic analysis method. in this research, seismic analysis of the dam-reservoir is studied as a wave propagation problem by using legendre spectral element method (sem). t...

  Purpose: Blast-induced traumatic brain injury (bTBI) is one of the causes of death or permanent   invalidity which can occur unexpectedly in both military and civilian populations. This study   set out to conduct a combined Eulerian-Lagrangian computational analysis of the interaction   between a single planar blast wave and a human head in order to assess the extent of intracranial   shock w...

Abstract A pseudospark (PS) discharge can generate an electron beam with a high current density. The be self-focused by ion channel and transported over long distance without the need for external magnetic field. Such features make it attractive to drive millimeter-wave/THz interaction circuits generation of high-power radiation from compact device. This paper presents experimental results on t...

The research group at the University of Perugia has been involved since 15 years in the analysis and design of microwave and millimeter-wave circuits in various technologies, from conventional (waveguide) to integrated (both hybrid and monolithic) circuits. The activity has been focused on both theoretical and experimental aspects. From the theoretical point of view an electromagnetic simulator...
