Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence by Lohmeyer, Whitney, Carlton, Ashley, Wong, Frankie, Bodeau, Michael, Kennedy, Andrew, Cahoy, Kerri

“…We also find that the accumulated voltages reached are high enough to compromise components in the amplifier system, for example, the direct current (DC) blocking capacitor. An electron beam test using a representative coaxial cable terminated in a blocking capacitor showed that discharges could occur with peak voltages and energies sufficient to damage active RF semiconductor devices.…”

Simulation of self-image interference in single mode-no-core-single mode fiber with COMSOL Multiphysics® by Mohd. Razali, Nazirah, Lokman, Muhammad Quisar, Zuikafly, Siti Nur Fatin, Ahmad, Fauzan, Yahaya, Hafizal

“…This paper proposes a simulation of self-image interference in a single mode-no-core-single mode fiber by using the wave-optics module in COMSOL Multiphysics® software. The beam propagation method is used to observe the self-image interference for different self-image indexes ranging from one to four indexes while the self-image length is obtained from the theoretical calculation before a simulation is carried out. …”
