Analysis of Rejection Properties of Meander Systems

Abstract

Influence of transverse asymmetry of meander systems on their frequency characteristics and rejection properties is considered. The model of the systems based on the multiconductor line method is used. Examples of calculated characteristics are presented. Properties of non-homogeneous meander structures, asymmetrical with respect to the longitudinal plane perpendicular to the central part of the system, are revealed. In the meander system containing electrodes with wide central parts of meander conductors and narrowed peripheral parts, the stop-band appears at q = p where q is the phase angle between voltages or current on neighbor conductors. At transverse asymmetry, the period of inhomogeneities along the meander conductor becomes two times greater with respect to the period of inhomogeneities at absence of transverse asymmetry, wherefore input impedance rapidly changes and the stop-band appears when phase angle q approaches to p/2. Increase of variation of characteristic impedances Z(0) or Z(0) or Z(p) followed by increase of the width of the stop-band.
