TU4B: Focus Session - High Field Magnetic Resonance Imaging Systems |
| |
|
Magnetic Resonance Imaging (MRI) is a high resolution non-ionizing (safe) tomographic technique that is extensively used for medical diagnostics and other related applications. It is based on creating two distinct energy states for the quantum spin of hydrogen nuclei in water molecules using a very strong static magnetic field. Better image resolution and higher tissue contrast can be achieved by increasing the strength of the static magnetic field. This Focus Session will provide a forum for discussions of some aspects of high field MRI systems including switching instrumentation, use of antennas to create the RF magnetic fields in the human body, the signal processing of MRI signals for images, and surgical techniques with MRI monitoring. |

WE1F: Special Session - 100 Years of Superconductivity (1911-2011) - Existing and Emerging RF Applications of Superconductivity |
| |
|
Superconductivity has many unique properties that can be used to produce RF, microwave and terahertz devices, circuits and systems with impressive characteristics. The year 2011 marks the 100th anniversary of the discovery of superconductivity. The discovery of superconductivity has been designated an "IEEE Milestone in Electrical Engineering and Computing". The year 2011 also marks the 25th anniversary of the discovery of High Temperature Superconductors (HTS), which can be operated at cryogenic temperatures that are relatively easily achieved. To commemorate these two anniversaries, this Special Session has been organized to provide an overview of the history and unique properties of the superconducting state and to provide details on some promising applications of potential interest to the microwave community. In the initial talk, the history of superconductivity will be reviewed very briefly and the properties of superconductivity that can be exploited in various applications, especially at microwave and terahertz frequencies will be described. The other talks in this session will address specific applications including: circuits which permit digital signal processing at frequencies up to and exceeding 40 GHz, extremely low noise figure detection of microwave and terahertz signals, and superconductor microwave circuits for read-out in emerging quantum computing applications. |

WE1H: Special Session - Memorial Session for Ted Saad |
| |
|
Theodore S. ("Ted") Saad graduated from the Massachusetts Institute of Technology and joined the MIT Radiation Laboratory, developing radar systems used during World War II. As the microwave electronics field flourished in the years following 1945, Ted applied his talents at the Submarine Signal Company, then as VP and Chief Engineer at Microwave Development Laboratories, and Sylvania. During the years at MDL and Sylvania, Ted was aware of a lack of professional communication among practitioner experts in the field of microwave theory and techniques. So in 1952 he applied his organizational skills to work within what was the Institute of Radio Engineers, to form a new technical professional group that is today the Microwave Theory and Techniques Society of IEEE. At the same time, he co-founded and was first Editor of The Microwave Journal. Ted and his colleagues within the fledgling Society started a new technical journal, later to become the IEEE Transactions on MTT, and Ted became the second editor of the Transactions in 1954. In 1955, he became co-founder, President, and Chairman of the Board of Sage Laboratories, which grew and flourished under his leadership. Ted played a key role in starting the Society's annual and highly successful Microwave Symposium. He chaired the National Administrative Committee of MTT in 1958, and served for many years as Historian of IEEE's Microwave Theory and Techniques Society. Ted was active in IEEE committees as well, including the IEEE Foundation, the IEEE History Center, and IEEE Technical Activities, and loved to say that the MTT was the "crown jewel" of IEEE Societies. It was, and its present reputation and success can be traced to his careful and active stewardship. |

WE2C: Focus Session - Recent Developments in Photonics for RF Front-Ends |
| |
|
Photonic devices and subsystems have been envisioned as enabling technologies for the generation, transmission, detection, processing, and control of microwave signals in future advanced systems for many years. Inefficiencies in the conversion from the microwave to optical domain and back, as well as added noise and distortion at these interfaces, have been key impediments to the full realization of the benefits of photonics. Recent developments have demonstrated great promise for the near term application of photonic subsystems in RF front-ends. This Focus Session will present some of these key developments and illustrate why the field of microwave photonics will continue grow and impact a diverse set of microwave applications. |

WE2F: Focus Session - Retrospective and Outlook of Computational Microwave Engineering |
| |
|
This Focus Session describes the evolution of time domain models of electromagnetic fields in response to the requirements of new and emerging technologies in the RF to optical range of the electromagnetic spectrum. The goal is assess the state-of-the-art in time domain modeling and to re-trace its evolution over the past thirty years in response to new technological developments, both in terms of novel applications and steadily growing computational resources. During their presentations, the session speakers will also highlight the numerous contributions of Professor Wolfgang J. R. Hoefer to the field of computational microwave engineering on the occasion of his 70th birthday. |

WE4B: Focus Session - Handset Impedance Tuners |
| |
|
Impedance tuners are on the verge of widespread use within mobile handsets to improve performance, compensate for environmental influences and shorten design cycles. As a new component in the RF designer's toolkit, the tuner specifications and value propositions are subjects of heated debate. Fundamental questions remain regarding a coherent approach to specifying tuner RF performance. This Focus Session will feature speakers from the leading tuner manufacturers who will present their perspective of the tuner market and requirements as well as their product capabilities. |

WE4H: Special Session - A Tribute to Professor Nathan Marcuvitz |
| |
|
Nathan Marcuvitz was an internationally recognized electro-physicist. During WWII he did ground-breaking work at MIT Radiation Laboratory when a national priority was the rapid development of microwave radar. During that time, he authored the Waveguide Handbook which is still considered a classic work characterizing microwave behavior and is well known to all of us working today in the fields of microwaves or optics. This Special Session will include friends and colleagues describing their experiences with Nathan Marcuvitz and his impact on their lives and careers. |
