Amateur Radio Astronomy Projects — Radio Signals from …

2 QEX – May/June 2010 ionosphere limits ground based reception below about 15 MHz and Jupiter itself does not emit these signals above 39.5 MHz — an upper limit determined by the strength of the

Introduction to Radio Astronomy

The EM Spectrum - Radio Radio signals are able to reach Earth and so many large radio observatories have been built to look at objects through this large portion of the EM spectrum. The pictures above shows the Milky Way galaxy in a 360 degree map view in both visible light (left) and radio radiation (right - 408 MHz). Remember that radio

Poynting Vector - University of Wisconsin–Madison

Poynting Vector Wave intensity I = time average over one or more cycle <sin2(kx - ωt)> = 1/2 then <E2> = Emax2/2 and <B2> = Bmax2/2 I av =u av c= E max B max 2µ 0 Define vector with magnitude= power per unit area (J/s.m2 = W/m2) Its direction is the direction of propagation of the EM wave Its magnitude varies in time Its magnitude reaches a maximum at the same instant …
