Abstract: A multilayer ceramic capacitor and a method of manufacturing the same. The multilayer ceramic capacitor includes a capacitor body including a dielectric layer and an internal electrode layer; and an external electrode disposed outside the capacitor body. The external electrode includes a lower layer positioned on a cross-section of the capacitor body to be electrically connected to the internal electrode layer, and an upper layer to cover the lower layer and positioned on the lower layer. The lower layer includes a first glass including aluminum (Al) in an amount of more than 0 atom % to 8 atom % or less with respect to a total amount of components of the first glass. The upper layer includes a second glass including aluminum (Al) in an amount of 10 atom % or more to 20 atom % or less with respect to a total amount of components of the second glass.

Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A spatial filter is provided. The spatial filter includes a first substrate having a first parasitic element configured to provide a filtering function and disposed on the spatial filter device, a second substrate having a second parasitic element configured to provide a filtering function and disposed under the spatial filter device, and a dipole antenna configured to transmit and receive radio waves in free space, coupled to each of the first parasitic element and the second parasitic element so as not to be aligned therewith, and disposed between the first substrate and the second substrate.

Abstract: Sensors and methods are provided that include a diamond material containing a nitrogen vacancy center, the diamond material being configured to be exposed to an environment comprising one or more gases, an optical light source configured to excite the nitrogen vacancy center of the diamond material with an optical light beam produced therefrom, a detector configured to detect a signal originating from the diamond material in response to the optical light beam exciting the nitrogen vacancy center, and the capability of analyzing the signal to identify a specific gas in the environment. Also included are levitated spin-optomechanical systems capable of elevating in a vacuum a diamond material containing a nitrogen vacancy center, applying microwave radiation to the diamond material for controlling and flipping the electron spin of the nitrogen vacancy center, and monitoring electron spin of the nitrogen vacancy center.
