An apparatus for controlling electromagnetic waves in an electromagnetic wave measurement device, the apparatus comprising:
- a transmitting antenna configured to generate electromagnetic waves through an aperture that controls a radiation pattern;
- a mode stirrer configured to reflect electromagnetic waves generated by the transmitting antenna by a plurality of unit panels;
- and
- a radio wave measurement part configured to measure electromagnetic waves transmitted through the mode stirrer,
- wherein the transmitting antenna generates a beam by a high-order mode,
- wherein a normal mode represents that one beam having the highest field value in a center radiates,
- wherein the high-order mode represents that three or more beams radiate in different directions, and
- wherein the three or more beams have uniform field characteristics.
A method for controlling electromagnetic waves in an electromagnetic wave measurement device, the method comprising:
- a process of generating, by a transmitting antenna, electromagnetic waves through an aperture that controls a radiation pattern;
- a process of reflecting, by a mode stirrer, the electromagnetic waves generated by the transmitting antenna by a plurality of unit panels;
- and
- a process of measuring, by a radio wave measurement part, electromagnetic waves transmitted through the mode stirrer,
- wherein the transmitting antenna generates a beam by a high-order mode,
- wherein a normal mode represents that one beam having the highest field value in a center radiates,
- wherein the high-order mode represents that three or more beams radiate in different directions, and
