Practical Design of Filters Using EBG Waveguides Periodically Loaded with Metal Ridges

The dispersion diagram of infinite periodic structures is useful for the practical design of waveguide filters. Starting from the dispersion diagram of a unit cell, it is possible to generate a finite structure with very similar passand stop-bands (gaps). However, truncation of the infinite periodic structure degrades the pass-band performance. In this paper, these impairments are overcome by m...

Cyclotron-resonance maser in a periodically loaded quadrupole transmission line.

A cyclotron-resonance maser (CRM) is implemented in a periodic quadrupole waveguide. The device oscillates at the fundamental and high harmonics of the cyclotron frequency. This CRM employs a tenuous low-energy electron beam ( approximately 10 keV, 0.2 A). The periodic structure consists of an array of disks along the quadrupole transmission line, hence it combines both azimuthal and axial peri...

Analysis of Periodically Loaded Suspended Substrate Structures in Millimeter Wave

Abstract—This paper presents a comprehensive study on the hybrid mode analysis of a periodic structure in a Suspended Microstrip and Broadside-coupled Suspended Stripline. The analysis has been use of Floquet’s theorem in special harmonics to express the field equations in various sub regions of the periodic loaded suspended substrate. Their characteristic equation is derived, using the Galerki...

Spontaneous Combustion of Paint Loaded Filters

(CSE) performed an analysis of the self-initiated thermal decomposition phenomenon of paint-loaded filters that has occurred on several occasions as reported by the Iowa Waste Reduction Center. By conducting a series of self-heating tests on samples of filters loaded with paint, CSE has shown that in selected circumstances the exothermic decomposition of the paint-loaded filters could lead to t...
