Electronic Circuits Lectures [PDF]

open access: yes, 1947
The two-electrode vacuum tube, or diode, consists of an electron-emitting cathode surrounded by a positive anode (plate). A plot of plate current (i{sub b}) vs plate voltage (e{sub b}) is shown. At low anode voltages, the anode current is limited by the repelling effect that the negative electrons already in the space have on the electrons just being ...

Synchronization by dynamical relaying in electronic circuit arrays [PDF]

open access: green, 2006
We experimentally study the synchronization of two chaotic electronic circuits whose dynamics is relayed by a third parameter-matched circuit, to which they are coupled bidirectionally in a linear chain configuration.

A straightforward spectral emissivity estimating method based on constructing random rough surfaces

open access: yesLight: Science & Applications, 2023
Spectral emissivity is an essential and sensitive parameter to characterize the radiative capacity of the solid surface in scientific and engineering applications, which would be non-negligibly affected by surface morphology.
