Spurious modes elimination for fractional differential equations [PDF]
PAMM, 2005 AbstractIn this paper, the stability of fractional differential equations is addressed. A criterion for the identification of spurious modes is derived. Two techniques for the a posteriori elimination of the corresponding solution parts are presented. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Collective inertia of Nambu-Goldstone mode from linear response theory [PDF]
, 2015 Background: Spurious zero-energy Nambu-Goldstone (NG) modes appear when the symmetry of a system is spontaneously broken. The Thouless-Valatin inertia, the collective inertia of the NG mode, contains important information concerning collective motion ...

Isoscalar dipole strength in ^{208}_{82}Pb_{126}: the spurious mode and the strength in the continuum [PDF]
, 2002 Isoscalar dipole (compression) mode is studied first using schematic harmonic-oscillator model and, then, the self-consistent Hartree-Fock (HF) and random phase approximation (RPA) solved in coordinate space. Taking ^{208}Pb and the SkM* interaction as a

Control of Higher Order Harmonics and Spurious Modes for Microstrip Patch Antennas
IEEE Access, 2018 In rectifying or active antenna systems, the higher order modes can hamper the system efficiency, and thus, the filter antennas are used to eliminate the harmonic radiation.

Influence of Spurious Waves on the Performance of Active Absorption Systems in Oblique Waves
Journal of Marine Science and Engineering, 2020 Existing active absorption systems do not take into account the spurious waves caused by the segmentation of the wavemaker. Thus, the theoretical estimated performance curves for oblique waves are only valid for infinitely narrow segments. In the present

Slow-Goldstone mode generated by order from quantum disorder and its experimental detection
Journal of High Energy Physics, 2021 The order from quantum disorders (OFQD) phenomenon is well-known and ubiquitous in particle physics and frustrated magnetic systems. Typically, OFQD transfers a spurious Goldstone mode into a pseudo-Goldstone mode with a tiny gap.

Combined Field Integral Equation Based Theory of Characteristic Mode [PDF]
, 2015 Conventional electric field integral equation based theory is susceptible to the spurious internal resonance problem when the characteristic modes of closed perfectly conducting objects are computed iteratively. In this paper, we present a combined field
