The Microwave Lab is involved in several collaborations in the field of superconductivity. Partners include the Center for Nanophysics and Advanced Materials in College Park, Md, Torino Polytechnique University in Italy, and Union Christian College in India.
Research in advanced materials is aimed at the next stage of technology. Electronics will some day be replaced by spintronics and quantum computing. Superconductivity will be a key technology for the post-electronics era, and the research that we do provides the scientific knowledge that will enable this revolution.
Your involvement in this field will concern the understanding of, and eventual utility of, nonlinearities in superconductive devices. Your experiments on superconducting devices will use a unique probing technique developed at Hope College. This technique has been published in Review of Scientific Instruments and has been used by Hope Students to make discoveries that are now published in the scientific literature.
We work with the group in Torino to generate and characterize colossal nonlinearities in transmission lines. We work with UCC to leverage the material chemistry by altering the doping to control the nonlinearities. Under the sponsorship of the National Science Foundation, these two projects have been on course to converge for the past two years, and this year will be combined into one project.
In doing your work, you will learn the tools of the trade in high frequency engineering including microwave test and measurement, electromagnetic design and analysis (EDA), and microwave device packaging.
This research will include some classroom instruction on the research topic along with required group meetings. A 42 hour training course (including much of the contents of PHYS 495, Microwave Engineering and Device Physics) will be given during the week prior to the start date and all accepted applicants are strongly encouraged to participate. Contact Prof. Remillard for details. Physics research requires physics knowledge and an enthusiastic record of taking physics courses is required. Gen Phys II Lab, PHYS 142, is a must. Students who have completed more than one year of college should be familiar with the principles of modern physics (PHYS 270). A higher proficiency in E&M (PHYS 342) is highly recommended.
