design, effective team participation and career preparation. Students
are expected to participate in hands-on design projects, develop
education/career plans and initiate development of the personal and
management skills necessary for life long learning.
Electrostatic and magnetostatic fields; Maxwell's equations;
introduction to plane waves, transmission lines, and sources
ECE 381 is structured to provide all students with the fundamental
concepts and analytical techniques associated with electromagnetics and
transmission line theory. Successful completion of this course will
allow a student access to all of the 400 level tech electives in the
electromagnetics and optics areas.
The goal of this course is to understand Maxwell’s equations and to
apply them to the solution of simple practical problems connected with
electromagnetic fields and waves. The students are expected to acquire a
working knowledge of the basic concepts of electromagnetism and to be
able to design simple components like rectangular waveguides
ECE 484/584
Antenna Theory and Design
Introduction to the fundamentals of radiation, antenna theory and
antenna array design. Design considerations for wire, aperture,
reflector and printed circuit antennas
ECE 484/584 is structured to provide all students with the fundamental
concepts and analytical techniques associated with antennas design and
analysis. Exposure to different types of practical antenna systems is a
major theme. Antennas now occur throughout our living environment.
Some common applications include communication systems (e.g.
satellite-to-earth link), mobile phones and wireless systems, radars,
navigation and guidance systems (e.g. GPS), antennas, radio astronomy,
remote sensing, hyperthermia for cancer treatment and magnetic resonance
imaging (MRI). Understanding
fundamentals of Electromagnetics is intrinsic to understanding how to
analyze and design various types of antenna systems for all of these
applications and more.

paraxial systems, third order aberrations, Gaussian beam propagation,
optical resonators, polarization, temporal and spatial coherence,
optical materials and nonlinear effects, electro-optic modulators.
Applications to holography, optical data storage, optical processing,
neural nets, associative memory optical interconnects.

Spectral decomposition of linear operators
ECE 581a
Electromagnetic Field Theory (Advanced Engineering Electromagnetics I)
ECE 581a is structured to provide all students with the fundamental
concepts and analytical techniques associated with engineering
electromagnetics. The material is a complete exposure to Maxwell’s
equations and their solutions for a variety of problems at an advanced
graduate level. This
theoretical study provides the student with the basis to deal with a
wide range of practical topics including microwave engineering,
millimeter wave engineering, optical engineering, antennas, sensors
remote sensing, electromagnetic interference and electromagnetic
compatibility. Understanding
the fundamentals of electromagnetics is intrinsic to understanding how
to analyze and design various types of components, devices, and systems
for all of these applications and more.
The course will consider Maxwell’s equations in rectangular, cylindrical
and spherical coordinates. A
variety of wave phenomena in simple and complex media will be discussed.
Plane wave, Gaussian beams, and current source solutions will be
treated. Basic scattering
from interfaces and guided wave problems will be introduced and solved.
The student will become conversant in standard definitions, special
functions, solution representations, and their use in solving canonical
problems. The class material will emphasize understanding and analysis
tools.
ECE 581b
Electromagnetic Field Theory (Advanced Engineering Electromagnetics II)
ECE 581b is structured as a sequential, second course that follows ECE
581a. In ECE 581a the fundamental concepts and analytical techniques
associated with engineering electromagnetics were introduced. In ECE
581b those concepts and the associated analytical tools are used to
investigate a variety of canonical propagation, scattering, and
diffraction problems. These problems include metallic and dielectric
waveguides, closed and open guiding structures, plane wave scattering
from cylinders, wedges, and spheres; line source scattering from
cylinders and wedges; and dipole scattering from spheres.
Asymptotic techniques including basics from the geometrical
theory of diffraction are included in the discussions.
As
with ECE 581a, ECE 581b class material will emphasize understanding and
analysis tools.
The material is a complete exposure at an advanced graduate level. This
theoretical study provides the student with the basis to deal with a
wide range of practical topics including microwave engineering,
millimeter wave engineering, optical engineering, antennas, sensors
remote sensing, electromagnetic interference and electromagnetic
compatibility. Understanding the fundamentals of electromagnetics is
intrinsic to understanding how to analyze and design various types of
components, devices, and systems for all of these applications and more.
Advanced scattering and diffraction problems that can be handled with
analytical techniques; Methods of solution of
boundary value problems in electromagnetics; Green's function and
eigenfunction expansion techniques; moment methods; asymptotics.
While basic problems such as plane wave scattering from cylinders,
spheres, and diffracting wedges are explained in ECE 581b, more
difficult problems, such as plane wave scattering from cylinders with
axial slits and spheres with circular holes and waveguide irises,
are treated analytically in ECE 688.
ECE 696a
Advanced Topics in Electrical Engineering, Fall 1995: High Frequency
Asymptotic Methods for Electromagnetics
All basic forms of high frequency asymptotic solutions of Maxwell’s
equations, including geometrical optics (GO), geometrical theory of
diffractions (GTD), uniform asymptotic theories (UAT), physical theory
of diffraction (PTD), physical optics (
ECE 696b
Advanced Topics in Electrical Engineering, Fall 2008: Computational EM
ECE 696b is structured to provide all students with the fundamental
concepts and basic numerical techniques associated with computational
electromagnetics (CEM), i.e., how to solve Maxwell’s equations on a
computational platform. Nearly all electromagnetics efforts, whether
academic, commercial, or government, rely heavily on modern CEM
software. The ability of CEM software to accurately predict the
electromagnetic behavior of complex systems from DC to light has
significantly impacted device and system design cycles, particularly
their cost. It is not uncommon now to be able to design, fabricate and
test with only one or two iterations to achieve a final product.
This course will discuss in some detail at least the basic three
methods: the finite difference time domain (FDTD) method, the finite
element (FEM) method, and the method of moments (MoM). The student will
become conversant in standard definitions, standard numerical
techniques, standard arguments for modeling in the time domain or the
frequency domain, standard limitations of CEM and standard approaches to
validate the CEM software.
The class material will be primarily a reading
course that will emphasize understanding and numerical tools.
