Innovative Electromagnetic Systems - from Idea to Practical Realization

Course Description

Design of electromagnetic systems ? differences between theoretically predicted behavior and actual behavior caused by non ideal properties of the components. Similarities and differences between design based on lumped elements and transmission lines and the design based on the full EM approach. Commercial EM packages ? are they really perfect? Example: Finite Difference Time Domain Method (accuracy, dispersion constraints, stability, boundary conditions). The constraints of classical technology and possible new solutions: periodic structures that behave as new materials, properties of which cannot be found in Nature. Example: Super lens and invisibility cloak. Practical problems in design of communication systems ? how to predict unwanted EM interactions? Example: Common mistakes and misunderstandings in design of active and passive devices and their incorporation in the system. Project -design of a small EM system.

General Competencies

The students will be able to design a smal EM system for special applications in RF and microwave regime

Learning Outcomes

  1. identify the differences between lumped and distributed elements in RF and microwave regime.
  2. explain construction of electromagnetic metamaterials
  3. design electromagnetic system based on standard components and special metamaterial components
  4. select appropriate numerical method for analysis of antennas or EM scatterers
  5. apply commercial full-wave simulator in analysis of engineering problems in RF and microwave regime
  6. develop a program for analyzing simple EM problems using finite-difference method or moment method

Forms of Teaching

Lectures

Each lecture unit is presented theoretically and practically, by experiments and computer simulations.

Laboratory Work

Four laboratory blocks are performed in groups of 4-5 students.

Experiments

In lectures five demonstration experiments are performed. Each experiment is videotaped and projected onto the screen so that all students can follow the course of the experiment.

Structural Exercises

Design and construction of a part of special EM system.

Programming Exercises

Design, writing and testing of simple electromagnetic program.
