Research and development in the terahertz portion of the electromagnetic spectrum has expanded very rapidly during the past fifteen years due to major advances in sources, detectors and instrumentation. Many scientists and engineers are entering the field and this volume offers a comprehensive and integrated treatment of all aspects of terahertz technology. The three authors, who have been active researchers in this region over a number of years, have designed Terahertz Techniques to be both ...

Telah diketahui bahwa bumi memiliki medan magnet yang dihasilkan oleh proses self-excited dynamo. Model dinamo kinematika dapat menggambarkan bagaimana suatu self-excited dynamo dibangkitkan dari interaksi antara aliran fluida dengan medan magnet. Namun, terdapat satu teorema anti dinamo yang mengatakan bahwa aliran yang planar tidak dapat menghasilkan medan magnet, yang dikenal dengan Teorema Aliran Planar (TAP) yang diberikan oleh Zel'dovich (1957).
Bachtiar, Ivers dan James (BIJ, 2006) telah membuktikan bahwa bukti untuk TAP tidak berlaku untuk ruang ...

Electromagnetic vibration energy harvesting devices introduces an optimization approach which is applied to determine optimal dimensions of the components (magnet, coil and back iron). Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate ...

This paper reports on the magnetic properties and electromagnetic characterization of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8). The La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8) materials were prepared using a mechanical alloying method. All the materials were made of analytical grade precursors of BaCO3, Fe2O3, MnCO3, TiO2, and La2O3, which were blended and mechanically milled in a planetary ball mill for 10h. The milled powders were compacted and subsequently sintered at 1000°C for 5h. All the sintered samples showed a ...
