What if the incoming radiation was polarized in the plane of the length of the stripe, there should be no resonance then, correct? Would such polarizsd radiation reflect specularly?Baluncore said:Not specular. The incident energy would excite your metal stripe resonator, which would then re-radiate the incident energy according to the radiation pattern of the metal stripe scatterer. The magnitude of excitation would be the product of the direction of energy arrival and the scatterer radiation pattern, polarisation is important.
A large field of dipoles can “glint” because all the small spherical wavefronts can reinforce to make a plane wave where the angle of incidence equals the angle of reflection.
If your scatterer is narrower than one wavelength, it could still be a half wavelength wide which would make a long linear array of resonant dipoles. That might glint in a particular direction. You need to reduce the width of the conductive stripe to below about one tenth of a wavelength to prevent glint. That is important for radar stealth design.
A subwavelength conductor patch is a small, thin piece of metal or other conductive material that is smaller than the wavelength of the electromagnetic waves it is interacting with.
A subwavelength conductor patch reflects specularly by acting as a mirror for electromagnetic waves. The patch must be smaller than the wavelength of the waves in order for it to reflect specularly.
Yes, a subwavelength conductor patch can reflect other types of waves, such as sound waves or water waves, as long as the patch is smaller than the wavelength of the waves.
Subwavelength conductor patches have potential applications in improving the performance of antennas, creating more efficient solar cells, and enhancing the resolution of optical devices such as microscopes and cameras.
One limitation of using subwavelength conductor patches is that they only reflect waves in a specific direction, known as the specular direction. They also have limited bandwidth and may only be effective for certain types of waves.
