SKA1-Low is a VHF radio telescope consisting of more than 130.000 dual-polarized antennas grouped in stations of 256 antennas each. Each station will observe the sky within 45 degrees from the local zenith by using an electronic beamforming. The indi

An active dual-polarized Log-Periodic antenna has been designed to meet the requirements of the low-frequency (50 – 350 MHz) radio telescope of the Square Kilometre Array (SKA). The integration of antenna and low noise amplifier has been conceived

Publikováno v: 2017 International Applied Computational Electromagnetics Society Symposium - Italy (ACES).

In the framework of the design of low observable aircraft, one of the most difficult problem is the numerical modelling of aeronautical air intakes with an — usually complex — arbitrary shape. Also the presence of radio absorbing material demands

In this paper, we present an incremental multilevel matrix filling and sparsification scheme for the method of moment (MoM) solution of the electric field integral equation at low and very low frequencies. The proposed scheme allows a strong reduc- t
