Question

Consider that we want to block a linearly polarized microwave by using a "polarizing grid" consisting of a metal sheet with long narrow slits of width d and spacing [delta] like that shown above. The wavelength of the incident microwaveW1 is much smaller than the width d of the slit openings. Then, compared to microwaves with wavelengthW2> d, the ability of the grid to block polarized microwaves of wavelength W1

A. Will be greatly diminished, but will be much more sensitive to the orientation angle of the slits, relative to the polarization direction.

B. Will be greatly diminished and will be much less sensitive to the orientation angle of the slits, relative to the polarization direction.    

C. Will become perfect-that is, the grid will become opaque.

D. Will be greatly increased, but will be much less sensitive to the orientation angle of the slits, relative to the polarization direction.

E. Will be greatly increased, but will be much more sensitive to the orientation angle of the slits, relative to the polarization direction.

Explanation / Answer

B. Will be greatly diminished and will be much less sensitive to the orientation angle of the slits, relative to the polarization direction.
