It is well known that a 3D ray tracing algorithm furnishes the ray’s coordinates, the three components of the wave vector and the calculated group time delay of the wave along the path. The latter quantity can be compared with the measured group time delay to check the performance of the algorithm. Simulating a perfect reflector at an altitude equal to the virtual height of reflection, the virtual time delay is assumed as a real time delay. For a monotonic electronic density profile we find a very small relative difference between the calculated and the virtual delay for both analytic and numerical 3D electronic density models. ; REGIONE ABRUZZO, PROVINCIA DELL'AQUILA, COMUNE DELL'AQUILA, UNIVERSITA' DEGLI STUDI DELL'AQUILA, DIPARTIMENTO DI FISICA (UNIVERSITA' DELL'AQUILA), EPS, ENEA, ISTITUTO NAZIONALE DI FISICA NUCLEARE (INFN), CNISM, CNR, ISTITUTO NAZIONALE DI GEOFISICA E VULCANOLOGIA, DMD, SPRINGER, EPL, EPJ B, McGRAW HILL, CAEN, LECROY, AMETEK, ASSING, BCC ROMA, CRISEL INSTRUMENTS, CANTINA TOLLO, WOLFRAM MATHEMATICA ADALTA DISTRIBUTORE UFFICIALE PER L'ITALIA, MICRON FOUNDATION, VACUUM SCIENCE, FLAMAR, REALE MUTUA ASSICURAZIONI AGENZIA DELL'AQUILA, ORTEC, PI, PERKIN ELMER, 2M STRUMENTI, LASER OPTRONIC, TAYLOR&FRANCIS GROUP, HAMAMATSU, FONDAZIONE CASSA DI RISPARMIO DELLA PROVINCIA DELL'AQUILA. ; Submitted ; L’Aquila, Italia ; 3.9.
