Help me find the latest method and technology in radio wave propagation

i've just started a basic course in antenna theory started by my college..our staff has set us an assignment..can someone help me get information regarding tat pls..

the assignment is to find out the latest methods and technology used in the following sub topics..
pls help me with ur expertise

Radio wave propagation
Modes of propagation, Structure of atmosphere, Ionosphere layers, Mechanism of bending of waves, Effect of earths Magnetic field on Radio wave propagation.

Virtual height, MUF, Skip distance, OWF, Ionosphere abnormalities, Multi-hop propagations, Space wave propagation, Super refraction

antenna measurementsImpedance, Gain, Radiation pattern, Beam width, Radiation resistance, Antenna efficiency, Directivity and Polarization Measurements.

Vertical incidence measurement of the ionosphere, Relation between oblique and vertical incidence transmission

thank u all..
