We study frequency locking and resonance of spiral waves in an active medium subjected to periodic forcing with adjustable frequency. The experiments are carried out with a modified Belousov-Zhabotinsky system whose excitability is light-sensitive. In the meander regime of compound rotation we find
Electromagnetic waves are used for detection of partial discharges (PD) in GIS (gas-insulated substations). A very wide frequency band up to 1.5 GHz is utilized for detection. There are three categories of electromagnetic wave which can be excited and propagate in coaxial cylindrical structures like
