This paper, presents the development of single mode cold cavity solver (SMCCS) code. SMCCS code computes the Frequency, Q-factor and axial field profile of eigenmodes in a gyrotron resonator. SMCCS has been developed using the cyclic coordinate search method along with golden section search. The novel optimization approach reduces computational complexity as it does not require computation of gradients of the radiation boundary condition. SMCCS has been used to compute the first-order as well as high-order axial modes in gyrotron resonators operating at 10-GHz, 170-GHz and l-THz. The results obtained art in good quantitative agreement with the experimental and numerical data available in the published literature.
