This book is the definitive resource for in-band full-duplex (IBFD) wireless systems. IBFD technology allows devices to transmit and receive signals on the same frequency at the same time, but has intentionally been avoided in a wide range of traditional systems. This is due to the significant self-interference that is generated by a transmitter co-located …
Sometimes as engineers we get depressed by the marketing hype applied to what are perceived as new technology opportunities. Smart Cities are an exemplar of this problem.

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 …

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. The Handbook of Next Generation Emergency Services by Barbara Kemp and Bart Lovett is about diffraction modeling and simulation. Scattering has gained …
