INTRODUCTION

Engineering Electromagnetics is one of six option areas in the undergraduate program and one of four research thrust areas in the graduate program offered by the Electrical Engineering Department. Described here briefly is the Electromagnetics program including the faculty and their interest areas, the undergraduate program requirements, the graduate program requirements, the research activities of the electromagnetics group and the laboratory facilities and equipment dedicated to studies in Electromagnetics.

The program in Electromagnetics varies in enrollment, graduating somewhere between 15 and 25 students each year. The thrust of the Electromagnetics program is applied and experimental as opposed to highly theoretical. The courses and activities described reflect this thrust and provide a brief detail of the program.


FACULTY IN ENGINEERING ELECTROMAGNETICS

The members of the EE department faculty with graduate degrees and expertise in Engineering Electromagnetics are listed below. This listing represents the largest special interest faculty group in the Electrical Engineering Department.

The research interest and experience of this group is varied and ranges from acoustics through ELF, microwaves and mm waves to optics. Much work has been done on the propagation of acoustic and electromagnetic energy, especially with respect to snow and forest environments. Experimental work is a departmental strength with the faculty having considerable experience in the design of special purpose hardware and in the processing of experimental data. Computational efforts are focused primarily on modeling of antenna patterns which can quickly be compared with those obtained experimentally with a computer and data acquisition system.


GRADUATE PROGRAM IN ENGINEERING ELECTROMAGNETICS

The graduate program in Engineering Electromagnetics is well structured and has been in place for several years. Many excellent graduate students have been involved in several significant research projects with two or three graduating from this program each year.

A Masters degree in Electrical Engineering requires the student to complete 45 quarter hours of study beyond a BS degree. Most full time students take 12-15 hours per quarter and finish the degree in three or four quarters. The specific requirements for an option in Engineering Electromagnetics are given. All MSEE students are required to take the two core courses in systems and computer modeling and 6 credits outside the department. For electromagnetics, these outside credits are in advanced mathematics. Major area courses for electromagnetics begin with EE540 which uses Harrington's "Time Harmonic Fields" for the text. Remaining major courses are in the areas of Antennas, Microwave Theory, Radar and Propagation. The catalog descriptions for these courses are given. Students may also use some senior level courses from a list of recommended electives in their MSEE program. These electives are either EE, Mathematics or Physics courses. Thesis work is the heart of the Masters Degree Program and is equivalent to taking three to five courses. A listing of recent Masters Theses in electromagnetics is given.

APPENDIX B

FUNDING GRADUATE STUDENTS

Three types of funding is available for graduate students in Electrical Engineering:

All three of these sources usually carry the same stipend: $2,500 plus tuition per quarter. Fellowships can be designated higher if desired. Fellowships have the advantage for the student in that the student can work full time on his/her program of course work and research and finish in one year. Research Assistantships require the student to work half time (20 hours per week) on a research project. Part of the research project normally becomes the student's thesis work. This position allows the student to finish in four or five quarters. Research Assistantships are funded by contract research. A list of Research Grants awarded to the Engineering Electromagnetics faculty is given.

Teaching Assistantships are funded either by the State of Michigan or by EE Department discretionary funds, and require the student to work half time teaching in the laboratories. Teaching Assistants usually require two years to complete an MSEE degree.

At this writing, the EE Department does not have any specific funds to offer Fellowships to students interested in Engineering Electromagnetics.
