Abstract: The present disclosure relates to a vapor cell and a vapor cell temperature control system, and more specifically, to a vapor cell and a vapor cell temperature control system which use a laser to control the temperature of the vapor cell without distortion of an electromagnetic field. The vapor cell according to an embodiment of the present disclosure may include a body provided with a penetration part, which is a space in which a reactive material is accommodated, and a black material provided on a part of an outer surface of the body. According to an embodiment of the present disclosure, there is an advantage in that the intensity and phase of electromagnetic waves in the micromagnetic field and millimeter wave band can be measured by minimizing distortion and removing noise caused by a temperature control device when measuring electromagnetic fields using an atomic system.

Abstract: A distance measuring apparatus includes an image sensor and an image sensor driver. The image sensor includes a photodiode, a first capacitor and a second capacitor, and a first transfer gate and a second transfer gate configured to transmit an output of the photodiode to the respective first and second capacitors. The image sensor driver is configured to complementarily drive the first transfer gate and the second transfer gate.

Abstract: A method of designing a frequency selective surface (FSS) filter, includes: calculating a candidate solution corresponding to a structure of the FSS filter and an objective-function value corresponding to a difference between a frequency response resulting from the candidate solution and a targeted frequency response; modifying the candidate solution into a trial solution in accordance with a genetic algorithm; and calculating an objective-function value with the trial solution to determine whether to include the trial solution in candidate solutions.
