The course is aimed first of all at presenting the basic knowledge of method and techniques of propagation in both guided structures and free space. Exercitations at the University Laboratories, using the Anechoic Chamber and microwave components, are developed to better understanding some propagation topics.
Propagation in guided structures: Transmission line equation – Wave propagation on a transmission line – Transmission line parameters – Characteristic Impedance – The lossless transmission Line - Voltage Reflection Coefficient – Standing Waves Ratio – Imput Inpedance of the Lossless Line – Resonance Conditions – Electromagnetic Theory of transmission Lines – TEM, TE, TM Modes – Coaxial Cable – Rectangular wave guide – Dispersion Law – Power in guide – Matching of transmission lines: Quarter-Wave Transformer – Impedance Matrix - Scattering Matrix - Smith Chart – Single Stub matching – Double Stub Matching. Free Space Propagation: Reflection, refraction and transmission of electromagnetic waves – Snell laws – Vertical and Horizontal Polarization - Brewster Angle – Direct ray, Reflection, Diffraction – Plane Earth Propagation – Real word propagation – Rough Surface Scattering - Fresnel zones – Trophosferic propagation - Fading – Trophosferic effects – Ionospheric propagation – Ionospheric effects – Effective Earth radius - Gaseous Attenuation - Introduction to propagation principles for wireless systems.
