Prof. Scarborough studies engineering electromagnetic (EM) structures, i.e. metamaterials, and their effects on wave propagation. His group is particularly interested in nonlinear and active metamaterials, which enable exceptional capabilities like one-way propagation, parametric amplification, and frequency-harmonic generation. These functionalities are critical to both civilian and defense applications such as radar, millimeter-wave communication, electronic miniaturization, and low-noise radio metrology.
ECEN 3400 - Electromagnetic Fields and Waves
Primary Instructor
-
Fall 2023 / Fall 2024
Electromagnetic fields are covered at an introductory level, starting with electrostatics and continuing with DC current, magnetostatics, time-varying magnetic fields, waves on transmission lines, Maxwell's equations and the basics of plane waves. The use of fields in inductors, capacitors, resistors, transformers, and energy and power concepts are studied.
ECEN 4634 - Microwave and RF Laboratory
Primary Instructor
-
Fall 2022
This course is a hands-on introduction to RF and microwave topics, from fundamentals including vector network analyzer (VNA) calibration and operation, power measurements, and antenna characterization, to system-level topics such as RADAR systems and superheterodyne links. Students work in small groups on weekly experiments based on both coaxial and waveguide setups. An understanding of electromagnetic waves (such as covered in ECEN 3400 and ECEN 3410) is assumed. The graduate version of the course (ECEN 5634) includes additional homework and exam problems and extended laboratory exercises compared to ECEN 4634. Same as ECEN 5634.
ECEN 5164 - Electromagnetic Metamaterials
Primary Instructor
-
Spring 2023
Enables students to design engineered structures to realize materials with desired electromagnetic properties that are difficult or impossible to achieve using conventional materials. Exact and approximate techniques are explored to develop an intuitive understanding of the electromagnetic response of these structures. Recommended prerequisite: ECEN 3410 (EM Waves and Transmissions) or equivalent course in fundamental electromagnetic theory.
ECEN 5254 - Remote Sensing Signals and Systems
Primary Instructor
-
Spring 2024
Examines passive and active techniques for remote sensing with emphasis on fundamental noise and detection issues from radio to optical frequencies. Emphasis is placed on electromagnetic wave detection, statistical signal and noise analysis, remote sensing system architecture, and hardware for remote sensing systems. Systems studied include radiometers, radars (real and synthetic aperture), interferometers, and lidars. Applications to detection and surveillance, Earth remote sensing, astronomy, and imaging systems are covered.
