Detection of negative energy: 4-dimensional examples [PDF]
, 2002 We study the response of switched particle detectors to static negative energy densities and negative energy fluxes. It is demonstrated how the switching leads to excitation even in the vacuum and how negative energy can lead to a suppression of this ...

Design of Spectrum Usage Detection in Wideband Spectrum Measurements
IEEE Access, 2019 We investigate the design of signal processing in wideband spectrum usage (SPU) measurements for efficient and smart dynamic spectrum access (DSA). In particular, we focus on spectrum usage detection (SPUD) in the experimental measurements. The detection

Prospects for radio detection of extremely high energy cosmic rays and neutrinos in the Moon [PDF]
, 2001 We explore the feasibility of using the Moon as a detector of extremely high energy (>10^19 eV) cosmic rays and neutrinos. The idea is to use the existing radiotelescopes on Earth to look for short pulses of Cherenkov radiation in the GHz range emitted ...
