Title: Air-Ground Channel Characterization: Fundamentals, Recent
Results, & UAVs
Author: Prof. David Matolak, University of South Carolina
(USA)
Description: This lecture describes the air-ground (AG)
channel and its characteristics. The topic is motivated by the growth in
air traffic, in particular the large growth in unmanned aerial systems
(UAS) or unmanned aerial vehicles (UAVs). Fundamentals and basic
characteristics of the AG channel are provided, as is a discussion of AG
channel model types. A large number of example AG channel results from an
extensive NASA measurement campaign are described. This includes
propagation path loss, delay dispersion, small-scale fading, inter-antenna
correlations, airframe shadowing, and wideband combined
deterministic-stochastic channel models. Areas for future research are
also provided.
Title:
Applying Wide-bandgap Devices to EV Battery Charges
Author: Prof. Kevin (Hua) Bai, Kettering University
(USA)
Description: Wide-bandgap (WBG) devices, such as SiC
and GaN, represent the future of power electronics due to the excellent
thermal performance and fast switching transitions. One of the best
applications for WBG devices is the battery charger in electric
vehicles. This video lecture discusses the application of WBG devices
to different battery-charger topology. Some challenges and design rules
are also detailed. |
