 SWS enables flexible dual-band use of a component as it allows bending
of the relation between frequency and wavelength
Generating Pass Bands and Stop Bands
 SWS structures can be designed to support frequency selectivity as it
renders possible to generate pass bands and/or stop bands
Overcoming Thermal Limitations of Power Rating
 Insufficient heat transfer from inner to outer conductor owing to low thermal
conductivity of dielectrics restricts power handling capability of rigid line
components
 SWS strongly increases thermal coupling of inner and outer conductor
Suspending Higher Order Mode Disturbance
 Cut-off frequencies of higher order modes (HOM) limit the usable frequency
