A benign approach is proposed for the highly efficient synthesis of cyclohexanone oxime through nonsolvent liquid‐phase oxidation of cyclohexylamine with dioxygen over supported TiO2/silica gel. The as‐prepared catalyst was characterized by Brunauer–Emmett–Teller (BET), Fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscope (SEM), X‐ray photoelectron spectroscopy (XPS), and...
In this paper, a novel compact triple-band frequency reconfigurable antenna array backed on EBG plate and based on integrated bias lines is proposed. It consists of a 4×4 reconfigurable antenna array, a wide-band feed network, a dual-band EBG plate and integrated bias lines. By applying a EBG structure, the distance between antenna array and reflective plate has been reduced by 76.0 percent. The proposed...
In this paper, far-field pattern and radiating near-field of broadband ridged horn antenna and array working in microwave band are simulated by commercial software HFSS and Feko. To research influence of platform to radiation characteristics of antenna, radiation pattern of single antenna and array is simulated using HFSS first, then imports the pattern into Feko as equivalent source to compute radiating...
