Analytical expressions of the Q-factor for the complete resonant mode spectrum of the equilateral triangular waveguide cavity

This Letter presents the closed-form expressions of the unloaded Q-factor in metallic cavities with equilateral triangular cross section, computed from its analytical resonant mode solutions. The obtained analytical formulas for the Q-factor extend the very restricted range of problems with closed-f...
