Numerical modelling of wave penetration in Ostend Harbour [PDF]
, 2010 The initial Ostend harbour entrance at the North Sea coast of Belgium is being modified and extended with two new rubble-mound breakwaters. Through an integrated study of the wave penetration in Ostend harbour, the waves are being acquired by prototype ...

Wave attenuation in mangrove forests; field data obtained in Trang, Thailand [PDF]
, 2012 Mangroves thrive in sheltered intertidal areas in the tropics and sub-tropics. Due to this position at the interface between land and sea, mangroves play an important role in the attenuation of waves.

Space-time-coding digital metasurfaces
Nature Communications, 2018 Current digital coding metasurfaces are only space-encoded. Here, the authors propose space-time modulated digital coding metasurfaces to obtain simultaneous manipulations of electromagnetic waves and present harmonic beam steering, beam shaping, and ...

Recent advances and perspectives on space-time coding digital metasurfaces
EPJ Applied Metamaterials, 2020 Within the overarching framework of space-time metastructures, digital metasurfaces based on spatio-temporal coding are emerging as powerful and versatile architectures for complex field manipulations, also in view of their inherently programmable nature.

Electromagnetic waves destabilized by runaway electrons in near-critical electric fields [PDF]
, 2013 Runaway electron distributions are strongly anisotropic in velocity space. This anisotropy is a source of free energy that may destabilize electromagnetic waves through a resonant interaction between the waves and the energetic electrons. In this work we

Absorptive Microstrip-Fed Slot Antenna With Wide Reflectionless Band by Loading Bandstop Filter
IEEE Open Journal of Antennas and Propagation, 2021 This paper presents an absorptive microstrip-fed slot antenna with a wide reflectionless band and high radiation efficiency. The proposed antenna consists of a microstrip-fed slot antenna, a quarter-wavelength coupled-line bandstop filter (BSF), and ...
