Electromagnetic Waves

Time-varying fields, displacement current, Maxwell’s equations, wave equation, retarded potentials, Poynting vector. Plane waves, polarization, propagation. Reflection and transmission. Transmission lines, ΤΕΜ waves, telegrapher’s equations. Waveguides, ΤΕ and ΤΜ modes, dielectric waveguides. Electromagnetic radiation and antennas, short dipole, half-wavelength dipole, antenna arrays, radiation pattern.

Upon successful completion of this course, students will be able:

• to recognize the differences between static and time-varying fields,
• to determine the electric-field using the magnetic-field intensity, and vice versa
• to use complex representations of electromagnetic quantities,
• to understand the properties and behavior of electromagnetic fields
• to know the impact of propagation media on wave properties,
• to solve simple problems involving reflection and transmission of waves,
• to solve problems pertinent to transmission lines, using circuit models,
• to determine the characteristics of waveguide structures that fulfill certain constraints,
• to study the properties of simple antennas.

Elements of the following courses are required:

• Physics,
• Mathematical Analysis ΙΙ.

Summative mid-term written assessment (25%) and summative
final written assessment (75%) in Greek. The adequacy of
theoretical knowledge, the ability to apply specific methodologies
and the ability to solve problems under specific time constraints
are tested. The evaluation criteria refer to the validity of the
answers, as well as to the degree of their clarity and completeness.
Oral exams are provided for students with learning difficulties. The
criteria can be accessed by students via the platform
eclass.uowm.gr.
