The results of the resonant frequencies are in good agreement with the experimental data. The input impedances are calculated and the results are presented. In principle, this method is applicable to a microstrip antenna with shorting posts in arbitrary locations.展开更多

The numerically computed results are compared with simulated results. The two gap-coupled circular microstrip patch antenna loaded with shorting post miniaturize the cross-sectional dimension of the radiating patch at the microwave frequency, which is useful for short range communications or contactless identification systems. The simulation has been performed using method-of-moments based commercially available simulator IE3D.展开更多

It discusses the origin of the short story in general and preconditions for the popularity of the new genre the Iranian literature of the 20th century, and also about the first successful collection of short stories that introduced it to the public. Also the development process of the short story and principle factors in every stage of its emergence as an independent genre of prose, as well as the thematic range are the main aspects among others to be analyzed in the article. It is historically documented that the Islamic state was established in 1979 after the fall of the Shah. And the very event had big impact not only on the social and political life of the country, but also on the cultural and literary life of the Iranians of the time. The significance of the revolution was such that it divided the literature to be known as the ＂pre-revolution＂ and ＂post-revolution＂ periods. Therefore this article is aimed to observe how this historic event had influenced the short story in particular and the distinct features of the works created during the two periods. The next period which stands out in the development of the short story is during the late 90s and the beginning of the 2000, where the genre experienced aesthetic innovations and experiments with new forms and styles. The distinct feature of the period is mainly in its topics it deals, among other the effects of the globalization and popular culture brought forth, isolated individual, urbanization, climate change and its destructive outcome and the social conflicts resulting from them. Such global issues caused the established writers to look out of their borders and open up to the concerns of the planet, and by doing so establishing new schools of thought and style among the writers of short story in modem Iranian literature.
