In this poster, a numerical model of spot pulsed current TIG welding for partially and fully penetrated weld pools is presented. Heat transfer and fluid flow in the weld pool driven by the combination of electromagnetic force, buoyancy force, surface tension gradient and latent heat are ... Per saperne di più
Lithium Niobate is a popular material for its non-liner optical properties, which is explored for various applications. Of many applications, use of these materials as photonic devices is indeed novel, in recent times. These photonic devices are set to revolutionise the silicon ... Per saperne di più
Dehydrogenation of ethylbenzene with a magnetite catalyst has been performed with a fixed bed flow type reactor under microwave irradiation. Microwave heating showed a temperature gradient in the catalyst bed. We analyzed an electromagnetic field and heat transfer in the microwave cavity ... Per saperne di più

近年来，一些研究人员基于金属波导的结构色散实现了各向同性的波导超材料，并研究了其各种各样的应用。然而，各向异性的波导超材料却没有得到深入的研究。我们利用金属平板/矩形波导在TEm模式下的结构色散，并在波导内部周期性交替填充两种不同的电介质A和B，并辅以细金属线连接上下金属板，从而可以将整个波导系统等效成二维TM偏振下的各向异性有效介质。我们发现在金属波导内沿着A-B多层介质的两个光轴方向存在两个不同的截止频率。当工作频率处在这两个截止频率范围内时，整个波导系统等效后的有效介质等频率曲线呈现出双曲函数的形式，即实现了双曲型波导超材料；当工作频率在较高的截止频率附近时 ...
