Airbus has been developing a mission and chaser concept for capturing and deorbiting the defunct Envisat satellite with different partners in the frame of ESA studies (e.Deorbit Phases A and B1). In the last e.Deorbit study called ‘Consolidation Ph

Ganymede is the only moon in our Solar System known to have its own global magnetic field, which generates a miniature moon magnetosphere inside the Jovian magnetosphere. Due to this unique characteristic of Ganymede, its auroral zone is also of part

The ability to withstand the harsh space environment is one of the key challenges in the design and construction of satellites. One of these special characteristics of space is the plasma environment encountered in orbit. In this paper, the system-le

We use Spacecraft Plasma Interaction Software (SPIS) simulations of the surface charging of the Jupiter Icy Moons Explorer (JUICE) spacecraft to study how the variable magnetospheric environment of Jupiter will impact the future JUICE particle and el

We report on microwave experiments with a metamaterial composed of pairs of metallic crosses. The transmission properties of the structure show a left-handed transmission band at frequencies around 10.2 GHz. The validity of the negative effective ind

We present a layout for the construction of strongly birefringent left-handed metamaterials in the THz domain. Using finite integration technique simulations, we show that the strength of the birefringence can be controlled by tuning the geometrical

We report an alternative approach for the design and fabrication of thin wave plates with high transmission in the terahertz regime. The wave plates are based on strongly birefringent cut-wire-pair metamaterials that exhibit refractive indices of opp

We present a freestanding bulk metamaterial operating in the THz frequency range. The implemented structure consists of pairs of metallic crosses for which the resulting composite medium exhibits a negative index of refraction at about 1 THz.

We report on terahertz wave generation using transient photoconductivity induced by femtosecond laser pulses in semiconductor surfaces. In particular the dependence of terahertz emission characteristics on pump pulse parameters like diameter and inpu
