Abstract:
In this paper, we show that the phenomenon of extraordinary
transmission through arrays of subwavelength holes,
present in the optical regime, is also present in the millimeter wave
range. After presentation of the theoretical foundations of the enhanced transmission, measurements of the transmission response have been performed on different samples by using a millimeter wave quasioptical vector network analyzer in the range between 45and 110 GHz. The prototypes have been fabricated in Aluminum
plates with several thickness and different hole diameters drilled
by using a laser machine. Good agreement between theory and experiment is obtained, with clear signals of the existence of resonant
transmission at wavelengths close to the period of the array.
Possible applications in frequency selective surfaces and near-field
imaging are envisaged.
