• Optical demodulator shuns local oscillator without loosing narrowband finesse

  28-09-2018 17:23 via electronicsweekly.com
  Side-stepping traditional laser local oscillator down-conversion techniques, Australian engineers are using acoustic interactions to retrieve frequency and phase information from Gbit/s modulated optical signals. “Our technique uses the interaction of photons and acoustic waves to enable an increase in signal capacity and therefore speed,” said Dr Elias Giacoumidis of the University of Sidney. “This allows ...

• Polyaniline + zinc ferrite = microwave absorption

  28-09-2018 13:35 via electronicsweekly.com
  A thin coating of a composite made from zinc ferrite and polyaniline absorbs microwave radiation in Ku band, according to researchers at  Anhui University of Science and Technology in China. The composites were synthesised by a two-step hydrothermal and in-situ polymerisation method, with Zn ferrite (2-30nm particles) used to adjust the impedance matching and improve ...

• EEMBC creates IoT Bluetooth power consumption benchmark for MCUs

  28-09-2018 10:57 via electronicsweekly.com
  Benchmarking consortium EEMBC has created a tool to measure the combined energy consumption of an IoT edge node’s sensor interface, processor, and Bluetooth LE radio interface. Part of the IoTMark benchmarking suite, it is called IoTMark-BLE benchmark. IoTMark-BLE models a node consisting of an I²C sensor and a BLE – radio through sleep, advertise, and ...
