Abstract :
We present a model of straight wire dipole scatterers loaded by arbitrary lumped loads in the dipole center. These particles can be used as inclusions of custom-design composite materials or electrically controllable metamaterials. The model, together with the Clausius-Mossotti formula and an analytical model for reflection and transmission in dipole arrays, allows to find loads required to realize the desired electromagnetic properties of the composite and estimate its realizability with the use of various bulk loads.
