چکیده
We investigate the use of parabolic equation (PE) methods for solving radio-wave propagation in polar ice. PE provide an approximate solution to Maxwell’s equations, contrast full-field solutions such as finite-difference-time-domain (FDTD) methods, yet a more complete model than simple geometric ray-tracing (RT) that are current state art simulating in-ice radio detection neutrino-induced cascades. PEs computationally efficient FDTD and flexible RT allowing inclusion diffractive effects modeling regions cannot be modeled with methods. present new approximation suited case. conclude may too simplistic their treatment ice properties, continued could overestimate experimental sensitivity neutrino experiments. discuss implications Askaryan-type detectors upcoming Radar Echo Telescope, two families experiments which these results most relevant. suggest investigated further applications.14 MoreReceived 22 December 2020Accepted 3 March 2021DOI:https://doi.org/10.1103/PhysRevD.103.103007© 2021 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCosmic ray & astroparticle detectorsParticle astrophysicsRadio frequency techniquesGravitation, Cosmology AstrophysicsCondensed Matter Materials Physics

کاربرد روش معادله سهموی در تحلیل مسائل انتشار امواج داخل ساختمان
With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...
متن کاملRadio Propagation Modeling on 433 MHz
In wireless network design and positioning it is essential to use radio propagation models for the applied frequency and environment. There are many propagation models available for both indoor and outdoor environments; however, they are not applicable for 433 MHz ISM frequency, which is perfectly suitable for smart metering and sensor networking applications. During our work, we gathered the m...
متن کاملPhase modeling of indoor radio propagation channels
Two models for generating phase of individual multipath components in an indoor environment, partly developed in [1], have been studied in detail. In the deterministic phase increment model (model I), phase of each multipath component is updated deterministically using several independent random scatterers. In the random phase increment model (model II), phase of each multipath component is upd...
