In this thesis, the Unstructured Transmission Line Modelling (UTLM) method is used to study wire problems with various configurations and structures. The analysis of multi-wire systems based upon local field solutions for wave equations is presented for the understanding of propagation mode within a wire bundle. The derivation of TLM scheme based upon unstructured triangular and tetrahedral meshes is presented, along with applications to the study of electromagnetic coupling and field transmission of canonical single-wire models and junction structures. The impact of wire configurations and positioning of wires within a bundle on the electromagnetic coupling into wires is investigated. Moreover, the radiation patterns of a Log-periodic dipole array (LPDA) antenna in different frequency bands is investigated. The accuracy of results presented in this work is validated by self-convergence with respect to sufficient simulation parameters and the efficiency of this method is evaluated based upon computational expenses.
