Multielement systems of double slots in rectangular waveguide with partial dielectric filling
Resonance characteristics of narrow transversal slots, energetic and directional characteristics of an antenna array (AA) with single transversal slots and double ones cut in a rectangular waveguide, partially filled with dielectric are investigated. In the case of the single transversal slots and double transversal slots a dielectric layer is parallel to broad walls of the waveguide. It was shown the possibility to construct an AA with double transversal slots the pattern without diffraction lobes and high level of radiation power in the frequency band.
Successive approximation method for the linear system of double longitudinal slots in a rectangular waveguide
An efficient approximation method is used to calculate energetic parameters and amplitude-phase distribution along a linear waveguide-slot antenna with double longitudinal slots in a broad wall of a rectangular waveguide having an arbitrary end loading. The approach is used when the E-field in slots is approximated with only one sinusoidal function. The mutual coupling of the slots over a waveguide and free space is taken into account, as well as the thickness of a waveguide wall and dielectric filling of the slots.
The effect of continuous exposure to low frequency electric fields on three generations of mice: A pilot study
Mice were allowed to mate, gestate, deliver and rear their offspring for 3 successive generations while being continuously exposed to 60 Hz electric fields. Mice exposed to vertical electric fields exhibited decreased body weights at 35 days postpartum and increased mortality, rates for 3 successive generations. Mice exposed to horizontal electric fields exhibited decreased body weights for 2 successive generations.
