Nanoantennas and metasurfaces tailored by electron beam lithography and substrate conductivity
Exposure analysis
In our analysis, the exposure dose k is a dominant factor that influences the size of the nanoantenna. To approximate the measurement results and analyze the nanoantenna dimensions, we use the relation \(r = -a \cdot \text…

Spacetime perspective of gravitational lensing in perturbed cosmologies
Our approach to cosmological lensing so far has followed a standard practice within the spacetime approach by making use of integral expressions to determine the paths of light rays. Because, as yet, we have been uninterested in the time along…
