SPINNER WAVELENGTH SHRINKING | STRETCHING

SWSSPINNER WAVELENGTH SHRINKING | STRETCHING

Shrinking Passive RF Components The size of most RF components depend on the wavelength which is usually determined by the operating frequency via: λ = c/f (c = velocity of light)

SWS shrinks the wavelength at the given operating frequency thus allowing reduction of size

Tailoring Dispersion Relations Conventional λ–dependent coaxial structures only work at a given frequency and odd multiples of it owing to the rigorous relation between frequency and wavelength

SWS enables fl exible 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 Insuffi cient 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 range and the maximum transversal dimension of a rigid line component, respectively

SWS can create wide monomodal TEM bands above HOM cut-off frequencies by introducing band gaps disabling HOM propagation and thus allowing "over-moded" operation w/o any HOM disturbance
