The investigations of an end-launcher transition in Carbon Fibre Reinforced Plastic (CFRP) WR90 waveguides is presented. The applicability of the feed for CFRP slotted waveguide antenna is addressed. Some of the aspects pertaining to the efficiency of CFRP slotted waveguide antenna and its use for radar applications are discussed. The results are presented in comparison with those obtained from the...
This work reports on the investigation and design of a waveguide feed for a slotted waveguide array antenna. The proposed method is presented for travelling wave waveguide antenna arrays that have been manufactured from carbon fibre reinforced plastic. The propagation of electromagnetic waves in these structures was simulated using the Finite Element Method. For the first time an anisotropic model...
The biological effect of electric fields on protein function and structure is a topic of increasing interest over the past few decades. With the proliferation of microwave devices the exposure to microwave radiation has become part of everyday life. The ubiquity of devices emitting electromagnetic radiation has highlighted concerns about the potential health effects. This work explores the dynamics...
Unfavorable weather conditions and prolonged electrical stress can lead to corona discharge and electrical arcing on high voltage insulators. The intensity of electromagnetic radiation emitted from an electrical arc is determined at different locations on cross-arm structures. Two common cross arm configurations available within the power network are studied. The results show that electrical arcing...
Partial discharge is the precursor of the insulator breakdown. The radiation pattern of partial discharge in dielectrics is investigated. It is envisaged that knowing the spectra of radiation emitted from dielectric cavities under electrical stress can be beneficial in designing partial discharge sensors. The radiation pattern is dependent on a multitude of parameters. Among these, the intensity of...
