Summary:We present a feasibility study of a real‐time visualization method for electromagnetic fields. When a resonant laser is used to irradiate gaseous atoms enclosed in a glass cell, the atoms absorb the light and immediately radiate as fluorescence. If a resonant laser and electromagnetic field are used to irradiate the gaseous atoms simultaneously, fluorescence of the light is stronger. The difference between the strength values of fluorescence of light can be used for electromagnetic field visualization. We succeeded in demonstrating a real‐time visualization of electromagnetic fields radiated from a horn antenna and an aperture of a waveguide in free space.
