In this paper, the trends from the last 10 years of inertial micro-generator literature are investigated and it is shown that, although current generator designs are still operating well below their maximum power, there has been significant improvement with time. Whilst no clear conclusions could be drawn from reported fabricated devices with respect to preferred transducer technology, this pap...

Coplanar radio frequency Schottky diodes based on solution-processed C60 and ZnO semiconductors are fabricated via adhesion-lithography. The development of a unique asymmetric nanogap electrode architecture results in devices with a high current rectification ratio (10(3) -10(6) ), low operating voltage (<3 V), and cut-off frequencies of >400 MHz. Device fabrication is scalable and can be perfo...

Pumping of electrons through nanoscale devices is one of the fascinating achievements in the field of nanoscience with a wide range of applications. To optimize the performance of pumps, operating them at high frequencies is mandatory. We consider the influence of fast periodic driving on the average charge transferred through a quantum dot. We show that it is possible to reverse the average cu...

Substrate-integrated waveguide (SIW) is a modern day (21st century) transmission line that has recently been developed. This technology introduced new possibilities to the design of efficient circuits and components operating in radio frequency (RF) microwave spectrum. Microstrip are very good for low applications but ineffective at extreme frequencies, involve rigorous fabrication concessions ...

The antenna is considered as one of the most fundamental elements in wireless communication systems, especially mobile devices. Desirable specifications antennas include covering wide range operating frequencies, while maintaining high quality system performance over whole frequencies. Therefore, ability tuning resonant frequency without altering its physical dimensions would be highly recommen...

Switches and rectification devices are fundamental components used for controlling the flow of energy in numerous applications. Thermal and acoustic rectifiers have been proposed for use in biomedical ultrasound applications, thermal computers, energy- saving and -harvesting materials, and direction-dependent insulating materials. In all these systems the transition between transmission states ...
