Summary: The dramatic increase in man-made radio frequency (RF) fields in the environment during the last few decades has led to public health concerns in many parts of the world. Specifically, questions have been raised on the safety of exposure to RF energy emitted from radar, television and radio communication systems, microwave ovens, video display terminals, and most recently, mobile telephones and base stations, Wi-Fi, and LTE. Wearable RF gadgets are prevailing. Wireless power transmission is a newer subject, which can involve high intensity exposures.

The IEEE EMF database now has more than 6700 original, peer-reviewed papers useful for public health risk assessment of RF exposure. Even there has been 70 years of research, and WHO indicated that scientific knowledge in this area is now more extensive than for most chemicals and current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields, controversy on RF safety continues. Both biological and engineering complexities make the validity of many studies questionable.

Summary: Since its initial conception, the transformer has been used in the most diverse applications where insulation and adaptation of voltage levels are demanded. In fact, this device is widely employed either directly or indirectly in all electrical engineering fields due its simple design for distinct power and voltage conversion levels. More specifically, the power transformer ensures the aforementioned characteristics in power systems applications, such as: ac power energy transmission and distribution, as well as medium-voltage machine drives. However, such applications are typically based on a bulky low-frequency device called Line Frequency Transformer (LFT).
Moreover, many applications normally use oil inside the LFTs for cooling and insulation purposes, which has direct impact on weight and volume and implies serious environmental issues. Another drawback lies in the low efficiency of LFTs, since they are typically designed with high current densities (as less copper is required) and operate at heavy load conditions that may result in operation with efficiency of 90%. In order to overcome such bottlenecks, many recent studies have tried to replace the conventional LFT for a power converter using a Medium Frequency Transformer (MFT) with operating frequency around thousands of hertz, thus reducing the intrinsic size and weight of its magnetics.
Such reduction is a must in medium-voltage machine drives, more particularly in electric railway application, since a more compact propulsion system is a requirement, resulting in the improvement of the transformer efficiency and reduction of the requested power with the same cargo capability. This advantage is especially desired in Electric Multiple Units (EMU) where the propulsion system is distributed among the locomotive’s cars.
Besides the voltage and weight reduction, the approach using MFTs must ensure harmonic mitigations, power factor correction, and fault suppression, among other functionalities.
This talk will present several SST topologies. Since all configurations must deal with high voltage levels due the innate SST propose, designers must choose the technology that best fits in their applications, considering the particular characteristics.

Radar not only has found widespread application in advanced driver assistance systems (ADAS) but also is one of the key technologies to enable environmental perception in autonomous driving. Compared with LiDAR and camera, radar technology provides reliable measurements of range, velocity and angle information of obstacles surrounding vehicle in all kinds of weather conditions. Unlike the traditional phased-array radar system which transmits via its antenna array a single waveform with different phase shift, multiple-input multiple-output (MIMO) radar can transmit multiple waveforms that may be chosen freely. As compared to traditional radar system with the same number of transmit and receive antennas, MIMO radar achieves significantly improved spatial resolution by exploiting waveform diversity. Due to its advantages, MIMO radar technology has been widely used in designing millimeter-wave radar sensors for ADAS and self-driving cars.

The Part I talk will focus on the fundamentals of MIMO radar as well as novel MIMO radar approaches with the emerging sparse sensing techniques. This talk will cover the radar basics, MIMO radar architecture and waveform design, sparse sensing methods in MIMO radar including compressive sensing (CS) based MIMO radar as well as novel MIMO radar approach using matrix completion (MC).

The Part II talk (October) will focus on the role of radar in autonomous driving and various aspects of automotive radar signal processing techniques. This talk will cover the radar system requirements and architecture for autonomous driving, principles of frequency-modulated continuous-wave (FMCW) radar, high resolution angle finding methods, “smart” radar sensors with machine learning, as well as unique problems associated with automotive radars for autonomous driving such as pedestrian detection.

Bio: Dr. Shunqiao Sun received his Ph.D. degree in Electrical and Computer Engineering from Rutgers, The State University of New Jersey in Jan. 2016.
