00:00:01 This is the beginning of the seminar by Professor Dr. Peter Anastosovski.

00:00:07 Probably pronounced incorrectly. Please say it correctly.

00:00:12 Anastosovski.

00:00:14 Anastosovski.

00:00:15 He's giving a lecture now here at Freestone on the papers he's published before,

00:00:25 and so-called referred to reference one and two here.

00:00:30 The meeting will be attended by Kevin Shambrook, Conrad Schneiker,

00:00:35 Ken Shoulders, and Steve Shoulders.

00:00:43 The position, I mean the angle of the reflecting sample, you will receive different polarization.

00:00:57 Nothing actually new.

00:01:00 What new is here to use the polarizer is if we take, we will allow this.

00:01:14 If this is the sample, this is the plane which is perpendicular to the sample,

00:01:29 the plane in which lays the incident laser beam,

00:01:38 the plane in which is a reflecting laser beam, you know, on the angle phi, phi.

00:01:51 We know both. We'll take it.

00:01:54 Well, if we turn the sample, so, around the H-axis, you know, what happens?

00:02:06 The reflected wave will have constant H, but changeable electric field, optical electric field.

00:02:17 H is magnetic field.

00:02:19 H is magnetic field of the optical beam.

00:02:25 The E is magnetic field of the reflected optical beam.

00:02:32 If we turn around, I mean if you move around the H, around the E,

00:02:46 around the E-axis, what the result is?

00:02:53 The result is that a reflected wave will have, will have constant electric field,

00:03:06 but the magnetic field will change.

00:03:10 The opposite situation is if we turn, if we turn the sample so that it's around H field,

00:03:22 then we have constant magnetic field of the reflecting light,

00:03:31 but will change the magnitude of the electric field.

00:03:40 What then can be used?

00:03:43 If the reflected wave will be used in any purpose, in any experiment, say, most simple one,

00:03:56 what is the absorption of certain compound?

00:04:02 If you let it go through the sample, then the absorption of that material,

00:04:11 you'll be sure that depends only in the first case of the magnetic field.

00:04:19 In the second case, you'll be sure that absorbance depends only on the magnetic field.

00:04:28 So by the first time, we see, we are sure how magnetic and electric properties,

00:04:37 how, I mean, what are the magnetic and electric properties of the cellular material.

00:04:44 That's the simplest case, the absorption of the light from the certain sample.

00:04:52 There are numerous other applications, you know.

00:04:57 This is not very, very important one.

00:05:01 Are you talking about the sample being behind that surface and absorbing this light?

00:05:08 No, I'm talking about the layer.

00:05:13 It can be the sample itself.

00:05:16 It can be the sample itself.
