A cardioid microphone is a directional mic: one that picks up more sound from the front than from the rear. The word "cardioid" means "in the shape of a heart". When the response pattern of such a directional microphone is plotted on a polar (360 degree) grid, it looks roughly like a heart.
Omni directional microphones cannot be changed to cardiod microphones. Even if you drill back holes behind the diaphragm.
In polar coordinates, p = 1 - sin(theta)
