    2.3 High-frequency Response
    Composite materials containing conducting sticks dispersed in a dielectric matrix have unusual properties at high frequencies. When frequency ω increases, the wavelength λ= 27πc/ω of an external electromagnetic field becomes comparable with the stick length 2α. In this case, one might think that the sticks act as an array of independent micro-antennas and the external EM wave should be scattered in all directions. Yet, the composite materials have well defined dielectric and magnetic properties at these frequencies, and we will demonstrate that. The description based on the "effective-medium" theory is possible because a thin conducting stick interacts with the external field like an elementary dipole. Therefore, we can still use the effective dielectric constant εe or effective conductivity σe=-iωεe/4π to describe the interaction of stick composites with the external electromagnetic wave. We note, however, that the formation of large stick clusters near the percolation threshold may result in scattering.
    Since conducting stick composites do have effective parameters for all concentrations p outside the percolation threshold, we can use the percolation theory to calculate their effective conductivity σe. However, the theory has to be generalized to take into account the nonquasistatic effects.
