Spurious modes of the TLM-condensed node formulation

IEEE Microwave and Guided Wave Letters, 1991
The TLM (transmission line matrix) method is based on temporal and spatial sampling of electromagnetic fields. As with he FDTD (finite-difference-time-domain) method, this results in dispersive effects and propagating spurious modes that corrupt the field solution.

Suppression of spurious modes in high power travelling wave tubes

1982 International Electron Devices Meeting, 1982
The main task of this work was to establish suitable means to suppress band edge oscillations in broad band coupled-cavity TWT's. The electric field flux lines in the slow wave structure have been calculated by means of conformal mapping. In the operating range, only transversal waves are existent, whereas at the upper cut-off frequency also E-modes ...

Stability and Spurious Kinematic Modes in Strain-Softening Concrete

1988
Consequences of the use of softening or brittle crack models for the stability of numerical simulations of the mechanical behavior of concrete structures are investigated. It is shown that brittle as well as softening crack models may trigger the formation of spurious kinematic modes.

Suppression of Spurious Modes in FBAR-Resonators

2007
Bandpassfilter aus FBAR-Resonatoren haben das Potenzial, die hohen Anforderungen aktueller und zukünftiger Mobilfunksysteme zu erfüllen. Durch ihre maximale Arbeitsfrequenz von etwa 10GHz und eine gute Temperaturstabilität bieten sie eine Alternative zu etablierten mikroakustischen Filtertechnologien.
