An Aligned-Gap and Centered-Gap Rectangular Multiple Split Ring Resonator for Dielectric Sensing Applications

This paper presents the design and development of a planar Aligned-Gap and Centered-Gap Rectangular Multiple Split Ring Resonator (SRR) for microwave sensors that operates at a resonance frequency around 5 GHz. The sensor consists of a microstrip transmission line loaded with two elements of rectangular SRR on both sides. The proposed metamaterial sensors were designed and fabricated on Rogers ...

Measurements of Relative Permittivity and Dielectric Loss Tangent of Fodel Dielectric with a Split-Post Resonator

The increasing use of computer-based software packages for designing RF/microwave circuits requires very accurate data about dielectric properties of materials used in the design. This paper presents results of precise measurements of relative permittivity and loss tangent of alumina substrates and Fodel dielectric 6050 used in thick-film photoimageable technology for fabricating microwave doub...

Multipactor Analysis in Dielectric Resonator Waveguide Filters

Multipactor breakdown analysis is presented in cylindrical dielectric resonator waveguide filter under its dual-mode behavior. The method of effective electron algorithm with combination of Monte-Carlo method is used to perform the simulation and predict multipactor breakdown thresholds.
