In this article, we proposed a method to analyze the voltages, currents, and imaginary impedances of the resonant modes in the square ring resonator by converting the square ring resonator to a guided wavelength transmission line.The impedance of the first four resonant modes of the ring resonator can be found and used as the coupling region for the bandpass response design with a high quality and...
This paper aims on the design and simulation of increasing the allowing angle a of the sun's rays applied in Fresnel lens of concentrated photovoltaic (CPV) concentrator. Contrasting to the pursuit of high efficient and high ratio in general system design, this paper proceeds the design of increasing the allowing angle of the sun's rays; contrasting to using planar Fresnel lens, this paper provides...
In this paper, the effects of the current distribution on the complementary split ring resonator (CSRR) are presented. The CSRR is etched off on the ground plane to provide dual-stopband characteristics over the desired frequency range. The dual-stopband characteristics can be determined by the dimensions of the CSRR. Current distribution shows the interactions of electromagnetic waves propagation...
Lithography is a key process in fabrication of semiconductors, especially, it plays the main role in the size of integrated circuit. Because of the diffraction limit, the size of lithography image cannot be shrunk less than wavelength. In this paper, we offer a practical method to get a subwavelength image by using visible light. This method is based on the localized surface plasmon among silver nanorods,...
There are not too many functions for an ordinary dynamoelectric door but the actions of open up and close down. This research improving the previous accident problems aims at developing a safer and more user-friendly dynamoelectric door. When the door is closing but there is someone nearby, the door will stop closing then run up. Also, with the perception device of fire accident and earthquake, when...
This paper presents an efficient method for power system static state estimation along with a statistical technique of bad data detection and identification. In the estimation process, the exponential function is utilized to modify the variances of measurements in anticipation of maintaining the estimation performance under the bad data scenario. Besides, with the aid of the proposed gap statistic...
