Abstract: A transmission line includes a substrate including insulator layers, a mounting electrode on a front layer of the substrate, a signal conductor, a first ground conductor, a first connecting electrode that electrically connects the mounting electrode and the signal conductor and is between the signal conductor and the first ground conductor in a laminating direction, a first inter-layer connecting conductor that is electrically connected between the mounting electrode and the first connecting electrode and is bonded to the first connecting electrode, and a second inter-layer connecting conductor that is electrically connected between the signal conductor and the first connecting electrode, is bonded to the first connecting electrode, and does not overlap with the first inter-layer connecting conductor when viewed in the laminating direction. The first ground conductor does not overlap with at least a portion of the first connecting electrode when viewed in the laminating direction.

Abstract: An atomic oscillator includes a light source, a gas cell including an internal space in which an alkali metal atom is sealed, and a photodetector to detect light emitted from the light source and passing through the gas cell. A radiation region of the light source is wider than a sectional area of the internal space at a distal end of the gas cell relative to the light source.

Abstract: An atomic oscillator including a light source, a gas cell including an internal space in which alkali metal atoms are encapsulated, and a light detector that detects light which has emitted from the light source and has passed through the gas cell. The alkali metal atoms encapsulated in the internal space are adhered, in a liquid state or a solid state, to at least an incident window, such that light incident on the incident window is reduced.

Abstract: In a non-reciprocal circuit element, electric power handling capability is improved, and leakage power between adjacent channels is reduced. In addition, balance is taken between reduction of noise between adjacent ports and an increase in insertion loss. A non-reciprocal circuit element includes a YIG ferrite (10) and a plurality of conductors (15) disposed on the YIG ferrite (10) and intersecting each other in an insulated state. A part of Y of the YIG ferrite (10) is substituted with at least any one element of Ho, Dy, and Gd, or a part of Fe of the YIG ferrite (10) is substituted with Co.
