Purified Si film formation from metallurgical-grade Si by hydrogen plasma induced chemical transport
Purified Si film is prepared directly from metallurgical-grade Si (MG-Si) by using hydrogen plasma induced chemical transport at subatmospheric pressure. The purification mechanism is based on the dif...

A two-dimensional broadband low-loss Luneburg lens has been designed based on the complementary metamaterials. The complementary I-shaped unit has been chosen as the basic cell due to its high resonant frequency, whose effective constitutive parameters are nearly constants at low frequencies. Numerical simulations are performed to determine the relationship between the unit geometry and the refraction index. The experimental sample has been fabricated and tested in a two-dimensional near-field microwave scanning apparatus, where the experiment and simulation results agree very well. Good focusing ability has been shown from the measured field distributions of the designed planar Luneburg lens. ©2009 American Institute of Physics
