METALLIC STRUCTURE FOR POLARIZING AND FILTERING AN ELECTROMAGNETIC WAVE AND AN OPTO-ELECTRONIC APPARATUS

摘要

PURPOSE: A metallic structure for polarizing and filtering an electromagnetic wave and an opto-electronic apparatus are provided to raise the transmissivity of the electromagnetic wave and to effectively filter or polarize the electromagnetic wave.;CONSTITUTION: A metallic structure includes a first metallic block(110) arranged inside and a second metallic block(120) arranged inside. The first metallic block and the second metallic block positioned in parallel are separated from each other in a predetermined distance. An electromagnetic wave enters the first metallic block and the second metallic block and a gap between the first and second metallic blocks. The electromagnetic wave has the distribution curve of a transmissivity by a wavelength after passing through the metallic structure. The distribution curve has a transmissivity peak value in one-to-one correspondence with a wavelength.;COPYRIGHT KIPO 2013
