Abstract

We performed experimental investigations aimed at studying in more detail the interdisciplinary problem of the effect of power loss for microwave signals transmitted through waveguides on the thermoelastic state of the latter. The waveguide temperature field was estimated using the developed mathematical models with differential equations of heat balance taking into account different operation conditions. The obtained temperature distribution may be applied to calculate deflected mode of waveguide as a whole and its conductive coating to ensure strength and hardness conditions.
