Abstract
With the advent of 5G communication systems, the problem of electromagnetic interference (EMI) has become more severe and needs to be curbed. This work aims to propose an analytical method for the design and development of an electromagnetic (EM) shielding structure for 5G mobile communication applications. An efficient teaching learning-based optimization (TLBO) embedded Equivalent Circuit Model (ECM) approach is used to optimize the FSS parameters in order to achieve the required shielding characteristics. The proposed structure has a minimum 10dB shielding effectiveness (SE) bandwidth of 1.0 GHz band with a 3.5 GHz central frequency. Moreover, the designed shielding structure works well for oblique incidence till 70 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">circ</sup> . TLBO embedded ECM model results are verified with the frequency-domain solver of Computer Simulation Studio (CST) software and a quite good agreement is noticed among TLBO and CST results.
