Electronic device for controlling radio wave focusing device and operating method thereof

An operating method of an electronic device, the operating method comprising:

• obtaining a magnitude difference by channels and a phase difference by channels based on a plurality of input radio waves generated by a radio wave generating device and a plurality of output radio waves output by a radio wave focusing device, wherein the magnitude difference by channels and the phase difference by channels are a magnitude difference and a phase difference between an input radio wave and an output radio wave determined for each channel;
• determining a lookup table (LUT) to which a control input is mapped, wherein the control input controls the radio wave focusing device to output a plurality of target radio waves based on the magnitude difference by channels and the phase difference by channels;
• obtaining a plurality of radio waves from the radio wave focusing device by applying the control input of the LUT to the radio wave focusing device;
• determining the plurality of radio waves and an error for the plurality of radio waves based on the plurality of target radio waves;
• and
• updating the LUT based on the error.
