Spurious regressions of stationary AR(p) processes with structural breaks [PDF]
, 2011 When a pair of independent series is highly persistent, there is a spurious regression bias in a regression between these series, closely related to the classic studies of Granger and Newbold (1974).

Spurious suppression techniques in integrated and embedded microwave components [PDF]
, 2021 To increase bandwidth and mitigate interference in a crowded electromagnetic spectrum, future microwave systems will move to higher operating frequencies. Because lumped elements perform poorly at high frequencies, designers use distributed elements for

Quasi-3D Model for Lateral Resonances on Homogeneous BAW Resonators
Micromachines, 2023 Lateral modes are responsible for the in-band spurious resonances that appear on BAW resonators, degrading the in-band filter response. In this work, a fast computational method based on the transmission line matrix (TLM) method is employed to model the ...

Hybrid-equilibrium elements with control of spurious kinematic modes
Computer Assisted Methods in Engineering and Science, 2023 A review is presented of a recent formulation of hybrid-equilibrium elements for modelling planar structural problems. The formulation is based on the use of polynomials of general degree to approximate internal stress fields and bounding side ...

High-Frequency and Spectrum-Clean Shear-Horizontal Acoustic Wave Resonators with AlN Overlay
Micromachines, 2022 By bonding the sub-wavelength-thick lithium niobate (LiNbO3) layer to high-phase-velocity (vp) substrates, such as Si, the shear-horizontal (SH) modes no longer couple with the bulk modes leaking into substrates.

Wideband Bandpass TM Cavity Filters With Wide Spurious Free Band
IEEE Access, 2023 Recently, the spurious self-suppression method has been introduced and applied to the bandpass TM cavity filters to improve their stopband performance. However, this method has the limitation of being applicable only to TM narrow-band filters. This paper
