I. Introduction
Electromagnetic scattering from wedges is a canonical problem, which has many important applications in radar cross section and antenna radiation. Various approaches have been applied to understand the behavior of scattering and radiation from wedges. The investigation of electromagnetic wave scattering from a slotted conducting wedge has been also performed in [1]–[3]. An finite-difference time-domain (FDTD) model is used to express the capacitance of a photoelectrical cell-mounted slot [4]. In this letter, we shall study the electrostatic field of a slotted conducting wedge by solving a pertinent electrostatic boundary-value problem. The Mellin transform and mode-matching will be utilized to obtain the capacitance of a slotted conducting wedge. Our solution is represented in a fast convergent series, which is compact and amenable to computation.
