Title Filter Design and Simulation Based on the Novel Artificial Metamatials
Abstract
With the development of communication and increasingly tense of the band, which makes the band-pass filter indicators become more and more demanding. Higher performance, smaller size, lighter weight, lower cost, has become a basic requirements to the new generation of filter. It is a unprecedented challenge for the filter design, and the traditional filter design methods have been increasingly unable to meet the development of modern technology. With the deepening of research on the Novel Artificial Metamatials, we discovered more and more magical properties of the Novel Artificial Metamatials, and that brought new ideas and methods to filter design. This article describes the significance and background of the Novel Artificial Metamatials, and its course of development and related applications. This article also explains the left-handed material negative refraction, anomalous Doppler effect, anomalous Cherenkov radiation effect, the perfect lens, the abnormal GoosHanchen displacement characteristics, and affect on the left-handed materials with point defects, vacancy defects, and surface defects. Finally, with HFSS software design a band-pass filter based on the complementary artificial medium structure with 2.1GHz center frequency, and describe the details of band-pass filter by changing the structure of the material of the basic artificial medium, size, etc
