ECEN 5134 - Electromagnetic Radiation and Antennas
Primary Instructor
-
Fall 2019 / Spring 2022 / Spring 2023 / Spring 2024
This course is introduction to antenna theory and antenna applications in applied electromagnetics. Elements of electromagnetic theory are first reviewed through the discussion of fundamental antenna parameters. Topics such as input impedance, radiation pattern, gain, radar cross section, near- and far-field, antenna temperature, and others are discussed first. The theory of operation of electric and magnetic dipoles, small and large dipoles, monopoles, and loops, as well as impact of different grounds on their parameters are discussed next. Other antennas such as bicones, helices, Yagi-Uda, microstrip patches, horns, reflectors, slots, spirals, log-periodics, etc. are also discussed. The fundamentals of array theory inclusive of linear, planar and circular topologies, coupling, beamforming, as well as elements of array synthesis are also discussed. Students will be exposed to the commercial software tools used to design antennas and will work individually or in teams to accomplish different project assignments. An understanding of Maxwell�s equations and electromagnetic waves (such as covered in ECEN 3400 and ECEN 3410) is assumed.
ECEN 5154 - Computational Electromagnetics
Primary Instructor
-
Spring 2020 / Fall 2022 / Fall 2024
This course is introduction to the frequency domain methods used in computational electromagnetics (CEM) for solving complex radio-frequency (RF) problems. The course starts with the review of electromagnetic theory and mathematical concepts used in CEM, followed by the introduction to the partial differential and integral equation based methods. Specifically, the fundamentals behind the finite difference method, finite element method, and method of moments are discussed and implemented to solve problems such as shielded microstrip line, charge distribution on metallic objects, waveguide modes, wire antennas, etc. Students will work independently and in teams to develop their own codes to solve given boundary value problems. The implementation of different methods in commercial software tools is continuously emphasized. An understanding of electrostatics and electromagnetic waves (such as covered in ECEN 3400 and ECEN 3410) is assumed.
