Research theme: Electromagnetic waves diffraction of a plane screen of a finite thickness with coaxial-sector apertures

 

 


Frequency-selective properties of a plane screen of finite thickness with coaxial-sector apertures

fig1 n

 

For the detailed analysis of the resonance properties of the screen, let us introduce the concept of an “equivalent electrical length”:

Fig.1 Frequency dependences of the absolute value of the reflection coefficient for different values of the screen thickness. Normal incidence.

The resonances of total transmission at the thickness screen 20 mm are observed under following conditions:

New resonances of total transmission of electromagnetic waves have been found to exist within that frequency range where resonances of the kind are impossible in the case of screens of finite thickness with a different geometry of the apertures.

It is shown that application of screens with coaxial-sector apertures in the capacity of frequency-selective surfaces allows broadening the operation frequency range of antenna system towards lower frequencies.

It has been found that the frequency-selective properties of a screen of finite thickness with coaxial-sector apertures are practically independent of the angle of incidence of a plane wave upon the screen surface within of 30 degrees.
