Abstract
Through-earth wireless communication has important applications for Defence, mining, and space exploration. Typical wireless signals are strongly attenuated by the ground and/or water; instead, we must use low frequency (< 1 kHz) fields, for which attenuation is relatively low. Magnetometers are an effective and compact means of detecting these fields. We are using cutting-edge nanofabrication techniques to develop new types of magnetometers that are small in size, light weight, and have low power requirements. I will discuss the development of our first on-chip integrated optomechanical magnetometer candidate for such applications.
About Physics Seminars
The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.
The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.
All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.
The seminars are open so there is no need to register your attendance.
