应实验室于彦涛老师的邀请，瑞典Lund University的Buon Kiong Lau教授将于7月12日来访进行学术交流，并于下午3：00-5：00 （地点待定）做学术报告，报告分为两部分：Seminar 1: Publish or Perish – surviving academic research 和 Seminar 2: Systematic Antenna Design with Characteristic Modes。请实验室的各位老师及学生准时参加。
Seminar 1:
Title: Publish or Perish – surviving academic research
Presenter: Buon Kiong Lau, Lund University, Sweden
Abstract:
Conventionally, new researchers learn about academic publication from those experienced in the field, including supervisors, senior colleagues and mentors. Apart from the normal requirements of novelty, significance, and technical correctness, many subtle skills and knowledge are also needed to be a successful author. It suffices not only to have good ideas and good results, since these need to be communicated through the writing in a proper manner for a paper’s contributions to be understood and critically evaluated.
In this seminar, I would like to share my perspective on academic publication based on the experience I have gained from being an active author and reviewer of several journals for many years. In addition, I have been a part of the editorial board for the IEEE Transactions on Antennas and Propagation (TAP) since 2010, and Guest Editor for three Special Issues/Cluster in TAP and IEEE Antennas and Wireless Propagation Letters (Lead Guest Editor for two of them). TAP is the most prestigious journal in the area of antennas and propagation and it is the journal with the second/third highest number of downloads in the IEEEXplore database.
Seminar 2:
Title: Systematic Antenna Design with Characteristic Modes
Presenter: Buon Kiong Lau, Lund University, Sweden
Abstract:
Conventionally, antenna engineering relies on customizing existing antenna structures to meet a set of requirements. Although advancements in computational electromagnetics and computational power over the past decade have help to shorten the design cycle, the heavy use of numerical optimization tools also tends to diminish the important roles of creativity, insights, and experience in synthesizing new antenna structures. In this context, the Theory of Characteristic Modes (TCM) perfectly interconnects modern computational electromagnetics with the creativity, insights, and experience of traditional antenna engineering. By extracting the inherent radiation properties of a structure, TCM allows for optimal antennas to be designed in a manner which is faster and superior to current complex antenna optimization algorithms.
TCM performs analysis on an arbitrary structure by solving a generalized eigenvalue equation derived from the Method of Moments (MoM) impedance matrix. This equation results in all the unique sets of currents (characteristic currents) and resonant characteristics (eigenvalues) of which the structure supports. These characteristic attributes can then be analyzed to design optimal antennas which meet a specific set of performance goals. These attributes allow new antenna researchers with little prior experience to follow a systematic, and intelligent design approach, rather than a relying on optimization algorithms or traditional brute force methods.
This seminar aims to illustrate how characteristic modes can be used as a systematic approach to design antennas to fulfill application specific requirements. TCM features in one or more EM software packages will be demonstrated. It is hoped that the seminar attendees will find the interest to explore the topic and discover for themselves how they can also take advantage of TCM in their own research.
