The microwave radiation emitted from the phase-center of a half-wave antenna, located in front of the LHM lens, is first focused on a spot inside the LHM lens and afterwards on point F, at a focal distance f from the interface with the lens. A Comparison between Different Schemes of Mic...

The property of an ellipse or hyperbola whereby lines drawn from the foci to any point on the conic make equal angles with the tangent to the conic at that point. The property of a parabola whereby a line from the focus to any point on the parabola, and a line through this point paral...
For simplicity, let's say that the hyperbola is centered at0,0with the following foci:Eat−c,0andFatc,0. So, the distance from each focus to the center isc. The distance from a general pointPx,ytoEis given byPE=x−−c2+y−02=x&plus...
and have come up with the diagram below, which is using just the center of the tube, but my secondary does have an offset of .135". I know this would move the secondary away from the focuser. Should I also subtract the .135" from the focal point making it .365, or leave it ...
The Focal Property of a Parabola Main Concept In mathematics, a locus is a set of points whose location satisfies specified conditions. If we plot a point P , called the focus, and a line l , called the directrix , that does not pass through P, the locus
The length of the focal chord of the parabola y^(2)=4x at a distance of 0.4 units from the origin is
but it is not symmetric around the focal point. The reflective surface of the OAP corresponds to a section of the parent parabola that is shifted away from the focal point. The section chosen depends on the desired angle and / or distance between the focal point and the center of the mirr...
