Abstract (en)

The waveguides (1, 2) have differing coefficients of thermal expansion. The transition section (3) between them, mechanically de-couples the differing thermal expansion coefficients.

Abstract (de)

Eine Hohlleiteranordnung weist einen ersten Hohlleiter (1) bestehend aus einem Material mit einem ersten thermischen Ausdehnungskoeffizienten und einem zweiten Hohlleiter (2) bestehend aus einem Material mit einem zweiten thermischen Ausdehnungskoeffizienten auf. Dazwischen befindet sich ein Übergangselement (3) zur mechanischen Entkopplung der unterschiedlichen thermischen Ausdehnungskoeffizienten der beiden Hohlleiter (1,2). <IMAGE>
