Connor Smith will defend his proposal, entitled: "Magnetic nanocomposites for power and RF applications" on Tuesday, 8/7, at 2:30 PM in Larsen 234. Refreshments and snacks will be provided!
With the Fall semester arriving, we will be having our IMG Kickoff Meeting on August 21, 2018 (day before classes start) from 11:45AM to 1:30PM. During this meeting, we'll discuss important IMG updates, introduce new members, recognize our accomplishments over the last year, and present some IMG awards. We may also try to take a group photo, so if you have a IMG polo or t-shirt, please wear it.
Please note, all IMG members are expected to attend this meeting. Pizza and drinks will be provided.
This week, the speakers for the IMG Seminar are:
Integrating microfabricated magnetic materials in 5G telecommunication systems. The microfabrication of ferrite structures on semiconductor substrates for mm-wave applications is an imminent necessity to the development of components in the 5th generation of telecommunication systems (5G). A team from IMG is conducting research in this area under the DARPA/MTO program called: Magnetic Miniaturized and Monolithically Integrated Components (M3IC). We have implemented fabrication and characterization techniques that required our group’s combined know-how on MEMS, microfabrication, magnetics, nanoparticles, transmission lines and RF. During this seminar we will present techniques to pattern >100 µm thick barium hexaferrite (BaFe12O19) films on semiconductor substrates, revealing material’s peak signal absorption associated with ferromagnetic resonances at 45.9 GHz.
IMG will be well-represented at the upcoming Hilton Head Workshop in June 2018:

This week, the speakers for the IMG Seminar are:
11:55-12:20 pm: Dr. Alexandra Garraud on "Extending the range of wireless power transmission for bio-implants and wearables"
12:20-12:45 pm: Todd Schumann on "Solely calcine controlled ferroelectric/memristor behavior in barium titanate"
There is an increasing demand for wireless power charging of mobile electronic devices, electric vehicles, biomedical implants and IoT sensor networks. Many of the already available wireless power transmission systems are based on inductive coupling and the size ranges in the cm’s scale, linked to the large surface area requirement. A competing technology is based on an RF approach, with small size chip but impractical power levels of pW to µW, and efficiency close to unity.
Congratulations to Daniel Alabi, Nicolas Garraud and John Varela for winning the Best Poster and the Best Demo Awards at the MIST 2017 Fall Meeting for their project "Chip-Scale MEMS Receivers for Low-Power Wireless Charging."
