A new concept of (open) TE011 cylindrical cavity
G. Annino, M. Cassettari, M. Martinelli
The confinement properties of the open structure formed crossing a circular waveguide perpendicular to a parallel-plate waveguide are discussed, highlighting the fundamental differ…
Properties of trapped electromagnetic modes in coupled waveguides
G. Annino, H. Yashiro, M. Cassettari +1
The existence of trapped modes in coupled electromagnetic waveguides is experimentally investigated for configurations with different degrees of symmetry supporting hybrid modes. T…
High frequency single-mode resonators for EPR spectroscopy enabling rotations of the sample about two orthogonal axes
G. Annino, M. Cassettari, M. Fittipaldi +1
A novel single-mode resonant structure which enables the rotation of the sample about two orthogonal axes is investigated in view of electron paramagnetic resonance applications. T…
Axially open nonradiative structures: an example of single-mode resonator based on the sample holder
G. Annino, M. Cassettari, M. Martinelli
The concept of nonradiative dielectric resonator is generalized in order to include axially open configurations having rotational invariance. The resulting additional nonradiative…
Open nonradiative cavities as millimeter wave single-mode resonators
G. Annino, M. Cassettari, M. Martinelli
Open single-mode metallic cavities operating in nonradiative configurations are proposed and demonstrated. Starting from well-known dielectric resonators, possible nonradiative cav…
Comment on "On the negative value of dielectric permittivity of the water surface layer" [Appl. Phys. Lett. 83, 4506 (2003)]
G. Annino, M. Cassettari
The recent interpretation of the positive resonance frequency shift in dielectric resonators loaded by water is reviewed. Instead of the invoked negative dielectric constant of wat…
