In this paper, we discuss the transport phenomena of electromagnetic waves ina two-dimensional random system which is composed of arrays of electricaldipoles, following the model presented earlier by Erdogan, et al. (J. Opt. Soc.Am. B {\bf 10}, 391 (1993)). A set of self-consistent equations is presented,accounting for the multiple scattering in the system, and is then solvednumerically. A strong localization regime is discovered in the frequencydomain. The transport properties within, near the edge of and nearly outsidethe localization regime are investigated for different parameters such asfilling factor and system size. The results show that within the localizationregime, waves are trapped near the transmitting source. Meanwhile, thediffusive waves follow an intuitive but expected picture. That is, theyincrease with travelling path as more and more random scattering incurs,followed by a saturation, then start to decay exponentially when the travellingpath is large enough, signifying the localization effect. For the cases thatthe frequencies are near the boundary of or outside the localization regime,the results of diffusive waves are compared with the diffusion approximation,showing less encouraging agreement as in other systems (Asatryan, et al., Phys.Rev. E {\bf 67}, 036605 (2003).)Comment: 8 pages 9 figure
