Abstract
Purpose – This paper aims to present a domain decomposition method to overcome the challenges posed by multi-domain, multi-scale high frequency problems. Design/methodology/approach – A hybrid finite element and boundary integral procedure is also presented that allows for domains to employ different solution methods in different subdomains. Findings – By decomposing large electromagnetic regions into smaller domains, the finite element method can cope with the simulation of electrically large problems. Practical implications – Real life examples demonstrate the accuracy and efficiency of the new method. Originality/value – The Robin transmission condition (RTC) is applied to link the domains and preserve field continuity on interfaces.
