In physics, a
homogeneous material or system has the same properties at every point; it is uniform without irregularities. A uniform
electric field (which has the same strength and the same direction at each point) would be compatible with homogeneity (all points experience the same physics). A material constructed with different constituents can be described as effectively homogeneous in the
electromagnetic materials domain, when interacting with a directed
radiation field (light, microwave frequencies, etc.).
