Electromagnetic (EM) bubbles (EMB’s), unipolar, super-short, and intense nonoscillating solitary pulses of EM radiation, can be generated in a gas of nonlinear atoms by available half-cycle pulses (HCP’s). We investigate how EMB’s characteristics (amplitude, length, formation distance, and total number) are controlled by the amplitude and length of originating HCP’s. We also predict shocklike wave fronts in the multibubble regime.
