IR Li2Ga2GeS6 nonlinear crystals were directly obtained with the composition of 40GeS2- 30Ga2Ss-30LieS, by the conventional melt-quenching method. The high depth digital image indicated that the obtained LizGa2GeS6 crystals showed a big size of 0.3 × 0.25 × 0.3 mm3. It was shown that the compound was very suscepfive to H20 with second harmonic observation. Besides, the glass-forming region of GeS2-Ga2S3- Li2S system was further studied by the conventional melt-quenching ***2-Ga2S3-Li2S glass-ceramics containing IR Li2Ga2GeS6 nonlinear nanocrystals were obtained at a more carefully controlled heating rate.

In this paper, the authors present the transmission line (TL) realization of one-dimensional subwavelength resonator formed by a pair of conventional right-handed material (RHM) and left-handed material (LHM). In such resonator, a novel reso- nant mode with the resonant frequency depending on the length ratio of the RH/LH TL sections occurs as a consequence of the full phase compensation due to the backward wave in the LH TL section. The theoretical circuit-model analyses are supported by simulation and experimental evidence on resonators with different RH/LH length ratios.

C-SiC coatings were prepared on stainless steel with magnetron sputtering deposition followed by Argon ion bombardment. These samples were implanted by 5 keV hydrogen ion beam. SEM, SIMS and IR transmission were utilized to study the mechanism and the stability of hydrogen retention of C-SiC coatings. Comparison was made between the samples with and without removing Argon by heating then followed by H^＋ ion implantation. The results show that removal of argon by heating can improve the hydrogen retention of the C-SiC coatings. The thermal stability of hydrogen barrier for the C-SiC coatings was investigated, it is found that the property of hydrogen retention for the C-SiC coatings is still good after heating at 573 K, but it becomes worse after heating at 873 K, and it loses after heating at 1 173 K.
