β¦ Synopsis
A comparison with the case of a dielectric nondispersive w x cluster 8 when the shift of the value of the plasma cluster velocity corresponding to the maximum reflectivity of the electromagnetic wave in the waveguide β€ is lacking shows 1 that the shift of the reflectivity maximum to smaller values of the cluster velocity is due to the existence of a doubledispersion mechanism: a plasma dispersion and a waveguide dispersion.

Probe-fed cylindrical dielectric resonator antennas CDRAs , with dielectric constant β s 37 and supported by an infinite ground plane, are simulated using the finite r element method. From this, closed form expressions are obtained for the resonant frequency, directivity, and unloaded Q-factor, appl
