Calculating the electric fields is crucial for determining several important physical parameters in many optical devices. Our recent work examined the optical absorption of a graphene film inside an optical microcavity by analyzing the electric field distribution through various dielectric environments, with the input laser source aligned perpendicular to the propagation direction. Practically, many studies have focused on investigating the optical absorption of absorber materials at different incident angles. These open up numerous questions related to controlling light-nanoobject interactions in optical systems, particularly within an optical microcavity. In this study, we focus on computing the electric field distribution in the resonant cavity under different incident angles. This approach provides a clearer understanding of the field distribution within the optical cavity and facilitates further calculations on the optical absorption of graphene sheets.
