The Influence of Dome Geometry on the Results of Modal and Buckling Analysis

Applied Sciences, 2023
The main purpose of this paper is to compare the results of modal analysis for two types of domes. The first one is a low-rise Schwedler dome. The second one is a high-rise geodesic dome.

Rigorous modal analysis of plasmonic nanoresonators

, 2018
The specificity of modal-expansion formalisms is their capabilities to model the physical properties in the natural resonance-state basis of the system in question, leading to a transparent interpretation of the numerical results.

Third Harmonic Cavity Modal Analysis [PDF]

, 2009
Third harmonic cavities have been designed and fabricated by FNAL to be used at the FLASH/XFEL facility at DESY to minimise the energy spread along the bunches. Modes in these cavities are analysed and the sensitivity to frequency errors are assessed.
