Ultra-Wide Band Diversity Antenna for Omnidirectional Coverage

Anja Skrivervik, Maxime Volery, Tatjana Asenov

In this paper, a 41 x 42.2 mm2 ultra-wide band (UWB) diversity antenna is designed to operate in the frequency band 5.45- 7.45 GHz with the isolation better than 15dB. To achieve omnidirectional coverage pattern diversity is applied. The proposed design is ...

Versatile spectral modulation of a broadband source for digital holographic microscopy

Christophe Moser, Tristan Colomb, Gaël Nardin

We demonstrate the potential of spatial light modulators for the spectral control of a broadband source in digital holographic microscopy. Used in a ‘pulse-shaping’ geometry, the spatial light modulator provides a versatile control over the bandwidth and w ...
