Electromagnetics laboratory

The Centre for Bio-Inspired Technology includes an Electromagnetics Laboratory equipped for all high-frequency measurement needs.

Location: Bessemer Building, B521

• Dr Peilong Feng (peilong.feng14@imperial.ac.uk)

Overview

Within this facility is a large, shielded, certified anechoic chamber, valid up to 34GHz, a 67GHz Agilent PNA with Cascade manual probe station and E-CAL automatic calibration for discrete SMA socketed use (up to 26.5GHz), an 8GHz 40Gs/s Agilent oscilloscope and a Picosecond pulse generator, as well as a host of other miscellaneous instruments. It is unique for the Centre to have access to such a chamber and it provides an ideal test facility for any project involving on-body or in-body antennas and indeed the communication between both. This, in conjunction with equipment such as the Agilent PNA and Dielectric Probe facilitates the use of anatomically and electromagnetically correct bio-phantoms to replicate the losses incurred when sensors and antennas are implanted in the body, leading to quicker prototype development and proof of concept.

Characterisation Services currently include:

• Onwafer probable devices to 67GHz
• SMA terminated prototypes (active or passive) to 26.5GHz
• Biophantom liquids and semi-solids from 200MHz to 26.5GHz
