Microwave diagnostics of ultracold neutral plasma

The microwave method is suggested to diagnose the ultracold neutral plasma. Based on the calculations of the dipole radiation, we derive the microwave scattering cross section of the ultracold neutral plasma, and microwave power scattered by the ultracold plasma is calculated as a function of time. The scattering cross section is nearly 10−11 m210−11 m2.
