Abstract

In this letter, a transverse slit within the signal line in a coplanar waveguide (CPW) structure is modeled as series inductance and parallel capacitance, and the simple formulas for the capacitance and the inductance are introduced. Also, a broadband harmonic‐suppressed filter (12.5–50 GHz), a band‐rejection filter, and a finite‐ground (FG)–CPW low‐pass filter (LPF) with this structure are demonstrated. © 2001 John Wiley & Sons, Inc.

A new equivalent circuit for inverters is presented. Using this circuit, expression for the elements of the coupling matrix of narrow RF band pass filters is derived. The derivation is based on frequency independent coupling assumed in the synthesis of narrow RF band pass filters. Our expression is

Decomposition and ordering processes in b.c.c. binary alloys are calculated by a pairwise interaction model. The interaction energy includes two terms due to a negative interchange energy V between the 1st neighbouring atoms which represents the ordering tendency and due to a positive interchange en
