Festival management innovation and failure

Abstract: Purpose – The paper seeks to examine the concepts, types and implications of festival innovation and failureDesign/methodology/approach – A review of extant literature is undertaken and examples of innovation and failure in three festivals are used to demonstrate the simultaneity and co‐dependency of innovation and failure in the process of festival managementFindings – It is apparent that many forms of program, market, service, organisational and financial innovation are available to festival managers Many involve risk of failure due to the resource dependency theory postulated in the literature, as well as more pragmatic reasons including bad weather and managerial incompetencePractical implications – Festival managers responses to the dual challenges of embracing innovation and avoiding failure will determine the future of festivals, so it is vital that knowledge is developedOriginality/value – There is limited literature on festival management innovation and failure and limited information avail

High-Gain Metasurface in Polyimide On-Chip Antenna Based on CRLH-TL for Sub-Terahertz Integrated Circuits.

Abstract: This paper presents a novel on-chip antenna using standard CMOS-technology based on metasurface implemented on two-layers polyimide substrates with a thickness of 500 μm. The aluminium ground-plane with thickness of 3 μm is sandwiched between the two-layers. Concentric dielectric-rings are etched in the ground-plane under the radiation patches implemented on the top-layer. The radiation patches comprise concentric metal-rings that are arranged in a 3 × 3 matrix. The antennas are excited by coupling electromagnetic energy through the gaps of the concentric dielectric-rings in the ground-plane using a microstrip feedline created on the bottom polyimide-layer. The open-ended feedline is split in three-branches that are aligned under the radiation elements to couple the maximum energy. In this structure, the concentric metal-rings essentially act as series left-handed capacitances CL that extend the effective aperture area of the antenna without affecting its dimensions, and the concentric dielectric rings etched in the ground-plane act as shunt left-handed inductors LL, which suppress the surface-waves and reduce the substrates losses that leads to improved bandwidth and radiation properties. The overall structure behaves like a metasurface that is shown to exhibit a very large bandwidth of 0.350–0.385 THz with an average radiation gain and efficiency of 8.15dBi and 65.71%, respectively. It has dimensions of 6 × 6 × 1 mm3 that makes it suitable for on-chip implementation.
