<正>在网络时代,传统外交人员的情报信息作用、议题能力设置和专业地位都受到挑战,而网络外交借助其意志结盟和互动性的特征,发挥着越来越大的影响力。美国驻华使馆积极响应和践行奥巴马政府"E化外交官"的号召,并借助博客吹风会、Web2.0外交、把Town Hall Meeting开到中国等新举措,大力开展对华外交,但奥巴马坦言从未上Twitter的事实令民众感到失望。

Using coplanar waveguide (CPW) to construct left-handed(LH) transmission line is more effective method than microstrip line. In this paper, a new type of LH transmission-line is proposed. It is composed with parallel embedded inductive and serial interdigital capacitor. Through extracting ß parameter of CPW transmission line, the region of LH transmission-line is obtained from 6 GHz to 14 GHz. The effective bandwidth is about 52% in 7.5 GHz-12.7 GHz. The backward-wave characteristic is validated by full-wave simulation.
