Abstract :
Two dissimilar metals, not brazed together, give high thermal contact resistance which further enhanced in vacuum if surface finishing is not good enough. Here, the effect of thermal contact resistance of a periodic structure supported with another dielectric material in vacuum has been studied and presented.
