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.

Fixed-Frequency Control of Piezoelectric Resonator DC-DC Converters for Spurious Mode Avoidance
IEEE Open Journal of Power Electronics, 2021 Piezoelectric resonators have shown promise as efficient, power-dense energy storage element alternatives to continue the miniaturization of DC-DC converters.

Lateral Spurious Mode Suppression in Lithium Niobate A1 Resonators [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2021 This work presents an improved design that exploits dispersion matching to suppress the spurious modes in the lithium niobate first-order antisymmetric (A1) Lamb wave mode resonators. The dispersion matching in this work is achieved by micro-machining the lithium niobate thin film to balance the electrical and mechanical loadings of electrodes. In this

On spurious instabilities on the β-planes with no mean flows [PDF]
Annales Geophysicae, 2010 Recent numerical calculations that suggest the existence of instabilities of the shallow water equations on the β-planes (both mid-latitudes and on the equator) are shown to be associated with spurious instabilities rather than genuine unstable modes.

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)

IEEE Journal of Microwaves, 2023 The effects of spurious modes on the performance of microwave systems is studied using a Monte Carlo algorithm based on randomized mode mixtures. A high power microwave launcher for the heating of fusion plasmas is used as an example, but the method can ...
