0:00:03 | perfect imaging with geodesic waveguide mike one column no problem any to someone comments on |
---|
0:00:09 | it |
---|
0:00:11 | the model fisheye lens sister of active |
---|
0:00:13 | it is reflected in the distribution |
---|
0:00:16 | with radial symmetry |
---|
0:00:19 | it was discovered by actual |
---|
0:00:23 | and it has an and making property |
---|
0:00:26 | for any point |
---|
0:00:28 | thus they use one |
---|
0:00:30 | the radiating from eight result to be for cues you know point |
---|
0:00:36 | called |
---|
0:00:37 | can you rate of the first one |
---|
0:00:40 | recently they are now has shown |
---|
0:00:44 | that the imaging capability of them actual fisheye lens |
---|
0:00:49 | which works well known in geometrical optics |
---|
0:00:51 | also holds for wavefile optics |
---|
0:00:55 | here we have of the representation of the electric field |
---|
0:00:59 | the magnitude of the electric field |
---|
0:01:02 | here we have a point source |
---|
0:01:05 | dispensers is to me age in and in another point called the drain |
---|
0:01:12 | where the energy is absorbed |
---|
0:01:15 | this can be better seen |
---|
0:01:17 | in these video |
---|
0:01:19 | what we see the source meeting and the drain absorbing |
---|
0:01:24 | collecting distribution |
---|
0:01:28 | in this paper |
---|
0:01:29 | we have used transformation optics to prove that the mystery feels in the spherical waveguide |
---|
0:01:35 | with the same perfect image and properties that have been shown for some feels them |
---|
0:01:40 | actual speech i |
---|
0:01:43 | for this propose we have to use this transformation from this original space x y |
---|
0:01:48 | z the to these images space such that the c d click on something are |
---|
0:01:53 | transformed in our equal consonants years in this space |
---|
0:01:57 | and the point to point correspondence between these surfaces exists or a graphic projection |
---|
0:02:03 | this is done for every seed equal constant plane |
---|
0:02:08 | and then we get this transformation that combine that with the primitive at under mobility |
---|
0:02:13 | distribution even them actual fisheye lens here |
---|
0:02:17 | leads to |
---|
0:02:18 | a distribution in this just base |
---|
0:02:20 | like this one |
---|
0:02:22 | that is system tropic non magnetic |
---|
0:02:25 | material with radial symmetry |
---|
0:02:28 | the feels parallel to the seed axis in this plane |
---|
0:02:32 | which are the feels show in the perfect imaging properties |
---|
0:02:35 | are transformed here |
---|
0:02:37 | in radial fields |
---|
0:02:40 | in order to isolate |
---|
0:02:43 | these fields in the certain region |
---|
0:02:46 | from the remaining is speech we used to |
---|
0:02:49 | conductor plates |
---|
0:02:50 | the feels |
---|
0:02:52 | are confined |
---|
0:02:55 | between the plates so we are creating a plan a waveguide with them actual fisher |
---|
0:03:00 | aligned distribution inside it |
---|
0:03:03 | and this is transforming the spherical wit waveguide |
---|
0:03:07 | here |
---|
0:03:08 | bounded by this to a spherical shells |
---|
0:03:14 | we conclude |
---|
0:03:16 | that in the wave optics framework perfect imaging properties of the martial fisheye lens can |
---|
0:03:22 | be replicated |
---|
0:03:24 | in a spherical wave guide |
---|
0:03:26 | we also conclude |
---|
0:03:27 | that the well-known correspondence between geodesic waveguide and number of active in the discrete distributions |
---|
0:03:34 | also apply here |
---|
0:03:40 | all these base the way |
---|
0:03:42 | for future experiments |
---|
0:03:45 | perfect imaging and super resolution |
---|
0:03:47 | with positive |
---|
0:03:49 | rough active index thank you |
