Ever noticed that your 5G signal can flicker on and off from metre to metre? It could be that you need a new phone, or, as NIST (the National Institute of Standards and Technology) have discovered, it may be caused by the humble tree. When companies launched their 4G services around 2012, users were …
With the recent release Nonlinear Design: FETs and HEMTs, we spoke to Peter Ladbrooke to find out the motivation behind his new book with Artech House. “Nonlinear Design, FETs and HEMTs is a detailed account of how the standard non-linear circuit model of these devices can be reformed to extend its range of validity and …
Your new book, Sustainable Power, Autonomous Ships and Cleaner Energies for Future Shipping, has just been published by Artech House, what was the original motivation for writing a book on this topic? Based on my international experience, and especially at IMO, I have for a long time seen that more and more focus has …
One of the benefits of doing a blog each month, apart from helping to sell a few books is that it helps identify areas where technology is changing in interesting ways. The impact of optical technologies on radio networks is a case in point. A modern telecoms network is a complex mix of radio and …
When Traces Melt: Figures 1 and 2 (Note 1) illustrate traces on two different boards. Each figure illustrates the trace at the moment it fuses (melts) due to a significant current overload. The fusing mechanisms are clearly different. So what was different? Here is the first hint. Assume there is a current that is just …
This book provides a comprehensive introduction into cryptography and the current state of the art. It starts with an overview about cryptography as a field of study and the various unkeyed, secret key, and public key cryptosystems that are available, and it then delves more deeply into the technical details of the systems. The goal …
This book is intended to be a practical guide for students, engineers, and researchers in electromagnetics with minimal background in machine learning. The book contains 9 chapters and is broken into two main parts. Part I contains the first five chapters that cover the theoretical principles of the most common machine learning architectures and algorithms …
The satellite communication landscape is evolving. The traditional services are not sustaining the growth that the space industry is used to, and new services are showing new promises. Broadband access is such an area encompassing two main applications, namely fixed broadband and mobile broadband. In these days where economics are becoming the deciding factor in …
We have assembled 20-plus years of knowledge into these pages. Starting with a historical background, this book covers: (a) PCB materials (copper and dielectrics) and the role they play in the heating and cooling of traces; (b) The IPC curves found in IPC 2152 along with equations and simulations that fit those curves; (c) Sensitivity …
Waves, either electromagnetic (EM) or acoustic (AC) interact with objects and scatter. The addition of incident and scattered fields form the total fields. Scattered fields include (but not limited with) reflections, refractions, and diffractions. This book is about diffraction modeling and simulation. Scattering has gained much attention because of the increase of wireless communication in …
