From: Interferometric control of the absorption in optical patch antennas
The interferometric control of the absorption in patch antennas summarized in normal incidence: adding two anti-symmetric modes excited from left and right leads to a complete cancellation, while adding even modes leads to an enhancement. For oblique incidence, this control is lowered, so that the even modes don’t completely cancel each other, and the odd modes are less enhanced.
