Usually horn antennas are used for the measurement of metamaterials or Frequency selective surfaces. Can one use some kind of patch antenna instead?

The aperture of horn antennas is usually large. This creates problems of requiring more distance and room for far field measurements. Is there a way, we can use patch antennas or other...

When measuring transmission parameters for metasurface, what should be the distance between the two horn antennas to have a far field illumination.?

In a generic setup, where metasurface is placed between the two antennas, what should be the minimum distance between the two antennas for accurate measurements: preferably in far field.?

How to calculate radius of a spherical wavefront of antenna at a particular distance?

For directive antennas, a wave front will propagate as spherical form at shorter distances, and as the propagation distance increases, its wavefront radius will get bigger. so at any particular...

What is the key feature in metasurfaces that makes them angularly stable?

I have seen unit cell designs that only perform at normal incidence while there are some designs that perform for a wide range of incidence angles. what is the reason or explanation behind this....

Thoughts and votes about HPV and SV40.

The Early genes 6 and 7 (E6/E7) of the HPV cause perturbation of the p53 and Rbp, respectively. This phenomenon is well-noticed in the SV40 where the large T antigen (TAg) abrogate the functions...
