| Transmission lines |
Getting started with some of the most commonly used transmission lines: two-wire, coaxial cable, twisted pair.
Circuit model of distributed parameters ,general equations, characteristic parameters (characteristic impedance, propagation velocity, attenuation and phase constants).
Attenuation, dispersion and crosstalk.
Transmission line in a circuit (reflection coefficient, standing wave ratio, input impedance).

| Waveguides and optical fibre |
Metallic waveguides: modes of propagation, cutoff frequency, single-mode band , attenuation and dispersion.
Optical fibre: structure and types, numerical aperture and acceptance cone, attenuation and dispersion, optical sources and receivers. |
| Radiowaves and antennas |
Characteristics of radiowaves: far field, radiation integral.
Antenna concept and fundamental parameters (radiation pattern, secondary lobe level, beamwidth, directivity, gain, polarisation, impedance).
Reception: power balance in free space (Friis equation), polarization loss factor.
