UHF SATCOM broadband CP antenna: moxon type bent-dipoles over a ground plane [PDF]
, 2011 In this paper, we investigate and compare two different antenna types for UHF SATCOM applications; proposed Moxon type (bent dipole) and conventional egg beater (loop) antennas in terms of antenna performance and physical size. Bent dipole and egg beater

Interacting Short Dipole Antennas
, 2022 This is a didactical text written to students of Physics and Engineering to investigate the interchange of electromagnetic radiation between two short dipole antennas. These phenomena can be observed in lessons and public sessions in the "Laborat rio de Demonstra es EWH" of the Institute of Physics of the University of S o Paulo (IFUSP). Key words:

Advanced Engineering Materials, EarlyView.The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Measurement of radio emission from extensive air showers
, 2009 A new promising development in astroparticle physics is to measure the radio emission from extensive air showers. The particles in the cascade emit synchrotron radiation (30 - 90 MHz) which is detected with arrays of dipole antennas.

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation
