A dynamic-relaxation formulation for analysis of cable structures with sliding-induced friction

Ian Smith, Nizar Bel Hadj Ali, Ann Christine Sychterz

In many cable structures, special types of joints are designed to allow cables to slide freely along the joints. Thus, a number of discrete cable elements are substituted by a single continuous cable that slides over multiple nodes. Continuous cables are e ...

3D-printed Ka-band Antenna Based on Stereolithography

Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged ...

Lightning-induced currents in buried coaxial cables: A frequency-domain approach and its validation using rocket-triggered lightning

Farhad Rachidi-Haeri, Mario Paolone, Emanuel Petrache

The aim of this paper is to present an experimental validation of a frequency- domain approach to the solution of the lightning electromagnetic field-to- buried cable coupling equations. The coupling to the inner conductor is evaluated using the concept of ...

Lightning-induced currents in buried coaxial cables

Farhad Rachidi-Haeri, Mario Paolone, Emanuel Petrache

We present a review of theoretical methods to compute lightning-induced currents and voltages on buried cables. The evaluation of such induced disturbances requires the calculation of the electric field produced by lightning along the cable path. We show t ...
