IEEE AP-MTT Columbus Chapter Presents:

3D Frequency Selective Structures:  Opportunities and Challenges

 Zhongxiang Shen

 Associate Professor, Nanyang Technological University, Singapore

Date: 10:00 AM – 11:00 AM, Thursday, July 7th, 2016 

Place:            ElectroScience Lab, The Ohio State University, MRC Conference Room #132, 1330 Kinnear Road, Columbus, OH 43212 (free parking is available)

Abstract: Conventional frequency selective surface consists of a two-dimensional (2-D) periodic array of unit-cells, which are either printed on a dielectric substrate or etched out of a conductive surface. These simple 2-D surfaces suffer from poor frequency selectivity and unstable response under different incident angles. Recently, an innovative concept of three-dimensional (3D) frequency selective structure (FSS) was proposed to alleviate the disadvantages of traditional frequency-selective surfaces. The new type of 3-D frequency selective structure is composed of a 2D periodic array of vertically placed microstrip lines, which is very promising for the realization of compact high-performance FSSs. This talk will introduce the proposed 3-D frequency selective structure. Mode-matching formulation for analyzing the structure will be briefly presented and equivalent circuit model will be employed to explain the operating principle of these three-dimensional FSSs. A number of design examples will be presented to demonstrate the high performance filtering response of 3D FSSs. Possible research topics for further investigation are suggested and existing challenges are also mentioned at the end of the talk.

Title:  “From Shades of Gray Situations to Black and White Solutions 

Abstract: Engineers and other technical professionals provide their greatest contribution to society by being ethical when solving problems and making decisions in the application of technology. However, ethical situations often are not black or white issues. Typically, various solutions appear to be shades of gray. In making ethical decisions, engineers need to be sensitive to how this will impact others. Although ethical behavior is based on personal values, there are guidelines to help professional engineers make ethical decisions. This presentation addresses ethics from a practical viewpoint and includes audience group exercises. It is designed to use team building skills and other engineering principles to change an ethical dilemma that appears to be shades of gray to a black and white solution based on proven ethical standards for our profession.

Presenter: Jim Watson is a Registered Professional Engineer and a Life-Senior Member of IEEE.

Jim Watson is a Registered Professional Engineer and a Life-Senior Member of IEEE.     Following a 36-year engineering and management career with Ohio Edison, he founded Watson Associates to incorporate professional skill development within existing university engineering technical classes. Watson Associates has directed the use of this program for more than 30,000 students at 7 major engineering universities.

As an international speaker, Jim has delivered more than 2,100 presentations in the United States, Canada, Europe, and Asia to a total audience of over 100,000, including more than 1,300 presentations to 65,000 students at 175 universities. Jim has also been a keynote speaker at 80 conferences and seminars for practicing engineers.

AP-MTT Mtg June 21

IEEE AP-MTT Columbus Chapter Presents:

Leveraging Advances in Computational Electrodynamics to Enable New Kinds of Nanophotonic Devices

 Ardavan Oskooi, Founder and CEO of Simpetus

Date: 11:00 AM – 12:00 PM, Tuesday, June 21st, 2016 

Place:             ElectroScience Lab, The Ohio State University, MRC Conference Room #132, 1330 Kinnear Road, Columbus, OH 43212

Abstract:

Advances in computational electrodynamics have the potential to enable fundamentally new kinds of nanophotonic devices which are based principally on complex, non-analytical wave-interference effects. Powerful, flexible, open-source software tools have now been made available for use in large-scale, parallel computations to model the interaction of light with practically any kind of material in any arbitrary geometry. These recent developments in computational capability make possible the investigation of various emergent structures, materials, and physical phenomena that were previously beyond the reach of pencil and paper analytical methods as well as less versatile and even less accessible commercial software tools. I will demonstrate how such advances in finite-difference time-domain (FDTD) methods for computational electromagnetics via an open-source software package known as MEEP can lead to entirely new designs for light trapping in nanostructured thin-film silicon solar cells as well as light extraction from nanostructured organic light-emitting diodes (OLEDs). I will then describe efforts by our startup to leverage scalable, high-performance computing (HPC) in the public cloud for large-scale device design.

AP-MTT Mtg May 27

Using Model-Based Parameter Estimation to Increase the Efficiency and Effectiveness of Computational Electromagnetics 

Edmund K. Miller 

Distinguished Lecturer, IEEE Antennas and Propagation Society

Date: 11:00 AM – 12:00 PM, Friday, May 27th, 2016  

Place:        ElectroScience Lab, The Ohio State University, MRC Conference Room #132, 1330 Kinnear Road, Columbus, OH 43212

Abstract:

Science began, and largely remains, an activity of making observations and/or collecting data about various phenomena in which patterns may be perceived and for which a theoretical explanation is sought in the form of mathematical prescriptions. These prescriptions may be non-parametric, first-principles generating models (GMs), such as Maxwell’s equations, that represent fundamental, irreducible descriptions of the physical basis for the associated phenomena. In a similar fashion, parametric fitting models (FMs) might be available to provide a reduced-order description of various aspects of the GM or observables that are derived from it. The purpose of this lecture is to summarize the development and application of exponential series and pole series as FMs in electromagnetics. The specific approaches described here, while known by various names, incorporate a common underlying procedure that is called model-based parameter estimation (MBPE)

An MBPE model of a frequency response can provide a continuous representation to a specified estimation error of a percent or so using 2 or even fewer samples per resonance peak, a procedure sometimes called a fast frequency sweep. Comparable performance can be similarly achieved using MBPE to model a far-field pattern. The adaptive approach can also yield an estimate of the data dimensionality or rank so that the FM order can be maintained below some threshold while achieving a specified FM accuracy. Topics to be discussed include: a preview of model-based parameter estimation; fitting models for waveform and spectral data; function sampling and derivative sampling; adaptive sampling of frequency spectra and far-field patterns; and using MBPE to estimate data uncertainty.
