High Heat Flux Micro - Electronics Cooling

The temperature of an electronics device rises fairly linearly with increasing device heat flux. This relationship is especially problematic for defense electronics, where heat dissipation is projected to exceed 1000W/cm in the near future. This paper study explored the benefit of cooling the electronics device using indirect refrigeration cooling system .In this system the heat sink in a prima...

Phase-shifterless beam-steering micro-slotline antenna - Electronics Letters

v) A novel beam-steering leaky-wave antenna that uses reactive loading capacitors along the leaky line is presented. The reactive loading varies the phase constant of the leaky line, altering direction of the main beam. A prototype was constructed and tested, demonstrating that a beam scanning angle of 23” is obtained by periodically loading the 0.06527 pF capacitors along the leaky line at 4 G...

Technologies and Materials for Micro and Nano-electronics

In the article technologies used in micro and nanoelectronics there are shortly described. Attention is devoted to lithography as a basic technology. Principles of electron and ion lithography are mentioned as well as progressive ion projection lithography. Some remarks to nanotubes as means of cold cathodes for vacuum electron tubes for nanoelectronics are presented.

Dynamic Thermal Simulation and Modelling of Micro- and Nano-Electronics

As semiconductor devices continuously get both smaller and faster, a profound analysis of the dynamic (time-dependent) thermal behaviour is becoming more and more important. In this article some basic concepts and numerical methods for thermal characterization in the frequency domain are explained. Two practical examples are given. First a simple model is presented for a small package mounted o...
