This paper presents the application of the Boundary Integral-Resonant Mode Expansion (BI-RME) method to the modeling of waveguide components comprising lossy dielectric materials. The proposed technique is based on the combination of the BI-RME method and of a perturbation approach. The BI-RME method yields the frequency response in terms of the generalized admittance matrix, expressed as a pole expansion...
This paper analyses the beam squint compensation of the Sardinia Radio Telescope, when used for deep-space Telemetry, Tracking & Command. The proposed technique consists in the displacement of the lower beam-waveguide mirrors to separate the transmission and reception beams of the antenna. Two design approaches are discussed. The first is a bottom-up method, very accurate and straightforward but...

Single Wall Carbon Nanohorns (SWCNHs) are innovative carbon nanostructures belonging to the thriving family of carbon nanotubes and fullerenes. They have being studied up to now mainly as non-cytotoxic drug carriers [1], but they are interesting for a huge number of applications such as electronics [2], hydrogen and methane storage [3] and renewable energies. In this paper we investigate their optical...
