Abstract :
An efficient method is developed for the rapid and accurate calculation of the potential Green´s function in the rectangular cavity. The proposed method is based on the Ewald sum technique and converts the slowly convergent cavity Green´s function into the sum of two exponentially convergent series. The transformed series achieves fast convergence with only a small number of terms in the calculation
