Polarization density refers to the vector field that represents the density of permanent or induced electric dipole moments in a dielectric material. It characterizes how an applied electric field influences the material's molecular dipole moments, leading to a separation of positive and negative charges within the material.

A vector field is a mathematical construct where each point in a space is associated with a vector, often used to represent physical quantities like velocity or force fields. It is fundamental in fields such as physics and engineering for modeling and understanding dynamic systems and spatial variations of vector quantities.
