The bandpass and notch (or band-stop) filters are designed to pass or block a specified range of frequencies. As a review, the primary frequencies are identified on the frequency response curves inFigure 1. As you can see, each of these filters has two cutoff frequencies, designated fC1and...
LOW-PASS FILTERS OF WIDE STOP-BAND BASED ON PHOTONIC BAND-GAP STRUCTURES一种基于光子带隙结构的宽阻带低通滤波器 Two novel low pass filters(LPFS) of wide stop band based on the structure of photonic band gap(PBG) and the structure of microstrip are proposed. The propo... LIU Hai Wen,SUN...

Silver gratings of hybrid structures are proposed, and their optical transmission properties are simulated by finite element method. The proposed structure is found to facilitate a broadband-enhanced transmission in the infrared region and exerts a band-stop effect in the visible region. The effects ...
The existence of frequency stop-bands, in which transmission of the vibro-acoustic energy is impossible, suggests that the periodic structures may be used for vibro-isolation. In any technical application, however, only a finite segment of such a structure can be used. This paper is concerned ...
Given the specifications of a band-pass filter (BPF) or a band-stop filter (BSF), the same can be translated to those of a normalized low-pass filter (LPF) by frequency transformation. Once the latter is designed, one can realize the BPF/BSF by using the same transformation in a revers...
