High temperature vulcanized (HTV) silicone rubber (SiR), due to its excellent electrical insulation, elasticity and temperature resistance, is used in cable accessories for HVDC cables. The space charge, generated under dc stress in SiR, would distort the local electric field, further influencing the characteristics of partial discharge and accelerating the insulation aging. This paper tried to modify...
In this paper, an approach based on the field equivalence principle for obtaining the information of the incident field from total field data is presented. In general, the incident field is not easy to know because it is related to not only the impressed source but also the characteristics of the transmitting antenna and the surrounding environment of the source. By using this approach, the incident...
The Maxwell fish eye lens has previously been utilised as an imaging device which exhibits sub-wavelength resolution. Here, we propose a new implementation based on surface waves which are excited in a dielectric slab over a metallic ground plane. Although the Maxwell fish eye lens has been shown to possess strong frequency dependence, this paper illustrates that for a single frequency, the proposed...
