“…Its different parts operate at different frequencies [19].Nowadays, the demand for super-wide band antennas for both long-and short-range transmissions for future ultra-wide band communication applications is very high. The term SWB (super-wideband) refers to bandwidth ratios of 10:1 or higher at a 10 dB return loss [20]. Many SWB antennas for advanced wireless communication in civilian and military systems are presented in the literature.…”

This paper presents a new shape (s-shape monopole) of a super wideband antenna using stepped meander lines, a quarter waveguide transformer feeding line, and a defected ground structure (DGS). The antenna will be used for multiple wireless communication applications like WIMAX/WLAN/ISM/UWB, and also for several wireless communication applications. The total dimensions of the proposed antenna are 35 mm × 35 mm × 1.57 mm or 0.36 λo × 0.36 λo × 0.016 λo, which are the corresponding electrical dimensions with free-space wavelength (λo) at the lower operating frequency. The antenna is designed and simulated into two steps: the first (Antenna 1) covers a bandwidth of 18.2 GHz, while the second (Antenna 2, using DGS) covers a super wide bandwidth of 37.82 GHz (3.08–40.9 GHz). The measured fractional bandwidth and bandwidth ratio of the antenna are 174.68% and 13.009:1, respectively, which is operating from 3.09–40.2 GHz. The maximum calculated gain and efficiency are 5.9 dBi and 92.7%, respectively. The time-domain performance is good due to the calculation of the system fidelity factor, group delay, and its linear and constant phase variation.

“…The spatial radiation pattern frequency reference is calculated by extracting the sound source's spectral centroid. (Tran D., et al 2012) Furthermore, the visual 'texture' of a sound-object is determined by the timbral features of the source sound. The adopted method to map timbral features into visual features derives from prior work by Giannakis and Smith (2000), which establishes a relationship between timbre and texture as summarised in the table below.…”

Approaches to Visualising the Spatial Position of ‘Sound-objects’

In this paper we present the rationale and design for two systems (developed by the Integra Lab research group at Birmingham Conservatoire) implementing a common approach to interactive visualisation of the spatial position of 'sound-objects'. The first system forms part of the AHRCfunded project 'Transforming Transformation: 3D Models for Interactive Sound Design', which entails the development of a new interaction model for audio processing whereby sound can be manipulated through grasp as if it were an invisible 3D object. The second system concerns the spatial manipulation of 'beatboxer' vocal sound using handheld mobile devices through alreadylearned physical movement. In both cases a means to visualise the spatial position of multiple sound sources within a 3D 'stereo image' is central to the system design, so a common model for this task was therefore developed. This paper describes the ways in which sound and spatial information are implemented to meet the practical demands of these systems, whilst relating this to the wider context of extant, and potential future methods for spatial audio visualisation.
