Abstract: Spin-photon interactions are commonly described using quantum-mechanical Hamiltonian models, whereas the influence of local EM-field overlap on the coupling response is less explored.This study presents a dipole-based fullwave EM analogue for investigating resonator perturbations inspired by spin-qubit systems.An effective oscillating electric dipole is introduced as an EM analogue of qubit-induced polarization within a superconducting coplanar waveguide (CPW) resonator.The effects of dipole resonance frequency, orientation, and spatial position on the transmission response are systematically investigated.The results show that the magnitude of the resonator perturbation is governed by the local dipole-field overlap and decreases as the dipole is displaced from the high-field region or rotated away from the dominant electric-field direction.A coupled-resonator configuration is furthermore used as a consistency test and exhibits hybridized resonant modes and avoided-crossing behaviour in agreement with classical coupled-mode theory.The proposed framework is an electromagnetic analogue rather than a quantum-state model, and is intended to provide physical and geometryaware insight for future integration with quantitative cQED parameter-extraction methods.
