Abstract: Recently, it has been shown numerically and by a semiclassical approach [Phys. Rev. Lett. 120, 093902 (2018)] that second-order exceptional points can appear in the spectrum of weakly deformed microdisk resonators by coupling of optical… read more here.

DOI: 10.1109/tuffc.2019.2942343
Abstract: Thin-film bulk acoustic wave resonators (FBARs) are of significant interest for wireless applications due to their good performance. To achieve excellent characteristics, the frame-like FBARs were previously invented by researchers in this field to suppress… read more here.

DOI: 10.1109/tuffc.2019.2958676
Abstract: Since surface acoustic waves (SAWs) are composed of multiple displacement components, their slowness curves sometimes exhibit a more complex shape rather than elliptical or hyperbolic. As a result, the parabolic approximation of 2-D coupling-of-modes (2-D… read more here.
