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.

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.

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

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).

Optical excitation of atomic force microscopy cantilever for accurate spectroscopic measurements
EPJ Techniques and Instrumentation, 2020 Reliable operation of frequency modulation mode atomic force microscopy (FM-AFM) depends on a clean resonance of an AFM cantilever. It is recognized that the spurious mechanical resonances which originate from various mechanical components in the ...
