Abstract
A general method to study the response of a system of multiconductors, lying above a perfectly conducting ground and excited by a HF electromagnetic field wave, is presented in this paper. The governing system of integro‐differential equations is solved by means of a numerical procedure based on a Fourier series transformation. It can be proved that the series in which the unknowns of the problem, namely the currents along the conductors, are developed converge to the exact solution and only few terms are needed. The obtained results have been compared with those of a widely employed scattering code, showing faster performances for a given accuracy. Therefore, the algorithm can be seen as a more accurate alternative to the classical transmission line theory (TL) for all the situations (short transmission line, interconnects, etc.) in which the line geometrical parameters and the frequencies of interest make TL a rough approximation.

Abstract
Purpose
The Olympic Games is the largest sporting mega event of its type, with deep cultural and historical roots. The event is short lived compared to the lifespan of the infrastructure required in host cities. The purpose of this paper is to examine models of adaptability in Olympic construction, using case studies in previous Olympic host cities of the Summer Olympic Games (Rome 1960, London 2012), to assess the impact of adaptability on future legacy.
Design/methodology/approach
A mixed methods approach (archival research, direct observation), was used in two case studies: Rome (Palazzetto dello Sport, Palazzo dello Sport), and London (London Olympic Velodrome, London Aquatics Centre). The case studies examined how adaptability was used in design to secure legacy.
Findings
In the selected case studies (Rome 1960, London 2012), adaptability has had a positive impact on the post-Games use of venues, all four of which remain in use today. However, there are multiple factors that contribute to post-Games legacy, and further research is necessary.
Research limitations/implications
Whilst some positive results were observed in this study, more research is necessary across a broader spectrum of sites and venues to make conclusive recommendations for architects designing for Mega Sporting events.
Social implications
The significance of this study to architectural practice, academia, and society is its potential to benefit future Olympic Games, International Olympic Committee policy, and be extended to other Mega Sporting events.
Originality/value
The originality of this research lies within its analysis of Olympic infrastructures and sustainability, of which there is a current lack of comparative studies in academic research.
