Multipactor saturation in parallel-plate waveguides

Michael Mattes, Francisco Edén Sorolla Rosario

The saturation stage of a multipactor discharge is considered of interest, since it can guide towards a criterion to assess the multipactor onset. The electron cloud under multipactor regime within a parallel-plate waveguide is modeled by a thin continuous ...

Modelling the interaction of electron clouds and microwaves

Michael Mattes, Francisco Edén Sorolla Rosario, Frank Zimmermann

This paper deals with the interaction of electron clouds with microwaves inside beam-pipes like the one of the LHC in CERN. The details of the model and recent results are presented during the conference. ...

Contribution to modeling multipactor and corona discharges in high power electromagnetic fields

Francisco Edén Sorolla Rosario

Multipactor and microwave corona breakdown are two high frequency discharges occurring within microwave components for space applications as well as within particle accelerators. The appearance of these phenomena results in the exponential growth of the el ...

Coupling matrix synthesis of dissipative microwave filters

Michael Mattes, Francisco Edén Sorolla Rosario, Diego Navarro Tapia

This study reviews the coupling matrix synthesis of dissipative microwave filters. It compares it to the synthesis of lossless transfer functions and shows that by correctly interpreting the mathematical operations in the lossless case, that is especially ...

Power Sub-Miniature (PSM) Connectors for Space Applications

Michael Mattes, Francisco Edén Sorolla Rosario

This paper presents a newly developed SMA-like connector for High Power Space applications that can withstand more than 1500 Watts in the P- and L-Band for a pulsed signal of 2% duty-cycle. This implies an improvement of 50 per cent compared to other power ...

Globally convergent algorithm to find the zeros of the cross-product of Bessel functions

Michael Mattes, Francisco Edén Sorolla Rosario

This paper shows the construction of an algorithm to calculate the roots of both, the cross-product of Bessel functions respectively of their first derivatives. The algorithm has shown globally convergent behavior for a large range of values of the argumen ...

NxN Coupling Matrix Synthesis of Dissipative Microwave Filters

Michael Mattes, Francisco Edén Sorolla Rosario, Diego Navarro Tapia

In this communication, the coupling matrix synthesis of dissipative microwave filters is analyzed and compared to the synthesis of lossless filters. A modified definition of the vector matrix product allows using the same synthesis procedure in both cases. ...

Corona Discharge in Microwave Devices: A Comparison of Ionization Rate Models

Michael Mattes, Francisco Edén Sorolla Rosario

In this paper we compare the predicted Corona breakdown power threshold obtained by different ionization rate models for an infinite parallel-plate waveguide. We point out the lack of a unanimous model of the ionization rate for RF fields and study the dif ...
