Recent advances in multipactor physics and mitigation
Abstract Recent progress made in the prediction, characterisation, and mitigation of multipactor discharge is reviewed for single‐ and two‐surface geometries. First, an overview of basic concepts including secondary electron emission, electron kinetics under the force law, multipactor susceptibility, and saturation mechanisms is provided, followed by a

Power limitations of magneto‐dielectric substrate microstrip antennas
Magneto‐dielectric substrates are an attractive avenue for improving antenna efficiency, bandwidth, and miniaturization. However, the consequences of incorporating such materials in antenna research and design have heretofore been uncharacterized.

High‐precision mathematical modelling of passive intermodulation in connectors
Abstract Passive intermodulation is an undesirable but unavoidable interference in communication system. Two high‐precision mathematical models are proposed to predict the passive intermodulation behaviour in coaxial connectors. Three kinds of coaxial connectors are selected as test samples.

An investigation into the passive intermodulation properties of space qualified materials [PDF]
Intermodulation products are spurious frequency components which are produced when two or more signals mix in nonlinear components and devices. Particularly in multi-signal environments like those encountered on satellites, the spurious frequency ...

Static I-V based PIM Evaluation for Spring and Fabric-Over-Foam Contacts [PDF]
Spring Clips and Fabric-Over-Foams (FOFs) Are Widely Used in Mobile Devices for Electrical Connection Purposes. However, the Imperfect Metallic Connections Tend to Induce Passive Intermodulation (PIM), Resulting in a Receiver Sensitivity Degradation ...

Practical Fixture Design for Passive Intermodulation Tests for Flexible Metallic Contacts [PDF]
Passive intermodulation (PIM) commonly exists in non-ideal metallic contacts. Since PIM typically represents an extremely low level of nonlinearity, it has not drawn enough attention over the years except for extremely high-power applications such as ...

Passive Intermodulation under Different Spring Contact Conditions [PDF]
Modularized designs have been widely used in today\u27s consumer electronic devices and flexible RF springs are used for electrical connections between the modules. In the meantime, aluminum alloy material becomes a common chassis option.

A New Model to Determine Passive Intermodulation Terms When Non-Contributing Carriers are Added to Classical Scenarios [PDF]
[EN] This paper provides a new theoretical model for the characterization of passive intermodulation behaviour when non-contributing carriers (i.e., carriers which do not directly affect the particular non-linear contribution under analysis) are added to

A groove gap Waveguide Iris Filter for V-band Application [PDF]
This work presents a V-band iris filter, based on recently introduced groove gap waveguide technology. In this technology, it doesn’t need to have electrical contact between two constituting metallic surfaces, as it is needed in conventional hollow ...
