Focusing on the Focusing Illusion... [PDF]

open access: yesSSRN Electronic Journal, 2013
The paper presents evidence that validate the focusing illusion. Specifically, the forecasted impact of a basketball championship on students’ subjective well-being was exaggerated because of their intense focus on the event. However, the self-reported states of being for life domains not closely associated with the focal event remained stable ...

A Tunable Zig-Zag Reflective Elastic Metasurface

open access: yesCrystals, 2022
In this paper, inspired by origami structures, we offer a very simple tuning method to overcome the limitations of general elastic metasurfaces, where only a certain functionality at a certain frequency range can be achieved, by designing a reflective ...
