Understanding the conditions under which Virtual Environment (VE) users experience a sense of presence may, in the long term, yield valuable insights into human cognition and psychology. More immediately, however, the general assumption is that a sense of presence impacts a user’s ability to perform a task and, therefore, that insights into presence offer a potential payoff in terms of task per...

This paper presents theoretical investigation of the electromagnetic wave tunneling and anomalous transmission around the trapped modes in a pseudochiral omega slab. The dispersion relation, the conditions of the trapped modes, and the evanescent wave coupling and tunneling in two different reciprocal pseudochiral omega slab structures are derived. The Berreman's matrix method is applied to obt...

3-D sound field reproduction systems can provide listeners with a sense of presence. In this study, we have proposed the 3-D sound field localization system using parametric loudspeakers. This system can easily represent sound images on the wall by using parametric loudspeakers that have a high directivity. In contrast, it is difficult to reproduce reverberant environments such as a concert hal...

Designing filter devices with precisely desired transmission spectra is of utmost importance in wave physics. For sharp (such as elliptic filters zeros), brute-force methods to directly optimize the spectrum face severe numerical challenges, while circuit models and coupled-mode theory apply only certain limits. The authors provide a set universal analytical criteria based on quasinormal-mode (...

We recently reported that direct subjective ratings of the sense of presence are potentially unstable and can be biased by previous judgments of the same stimuli (Freeman et al., 1999). Objective measures of the behavioral realism elicited by a display offer an alternative to subjective ratings. Behavioral measures and presence are linked by the premise that, when observers experience a mediate...

We report a detailed magnetic and structural analysis of highly reduced Co d displaying an anomalous Hall effect (AHE). The temperature and field dependen transmission electron microscopy clearly establish the presence of nano-sized s clusters of ~8–10 nm size in the films at the interface. The co-occurrence of s AHE raises questions regarding the use of the AHE as a test of the intrinsic natu ...
