    "abstract": "We used two-dimensional Finte-Difference-Time-Domain (FDTD) software to study\nthe transition behavior of nano-particles from scatterers to an optically\nuniform medium. We measured the transmission efficiency of the dipole source,\nwhich is located in the high refractive index medium(index=2.00) and\nencapsulated by low index resin(index=1.41). In an effort to compose\nindex-matched resin and to reduce internal reflection, high-index\nnano-particles are added to low-index resin in simulations of various sizes and\ndensities. As the size of the nano-particles and the average spacing between\nparticles are reduced to 0.02 lambda and 0.07 lambda respectively, the\ntransmission efficiency improves two-fold compared to that without\nnanoparticles. The numerical results can be used to understand the optical\nbehavior of nano-particles and to improve the extraction efficiency of high\nbrightness light-emitting-diodes(LEDs), through the use of nano-composite\nencapsulant.",
