New loss mechanism for global 4G roaming

A loss mechanism that has not been an issue in previous mobile handset antennas will become important for global 4G roaming, according to results of experiments carried out in Aalborg, Denmark.

Neuron circuit may enable pitch perception applications

The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit operates according ...

Microwave multi-tool

A resonator element that can simultaneously act as both a filter and antenna has been developed as a step towards creating PROMFAs - the microwave circuit equivalent of an FPGA.

Knee-deep sensing

A new, non-invasive technique to track the motion of knee bones in 3D with a very high precision has been presented by researchers in Australia. By employing a single-element ultrasound sensor and a fast image registration ...
