This paper presents the design, fabrication, and performance of a 76-77 GHz high isolation single-pole triple-throw (SP3T) switch implemented by coplanar waveguide (CPW) GaAs PIN-diode MMIC technology. The switch MMIC was developed for an electronically scanning antenna module specialized for use in an automotive holographic radar system. A PIN-diode pair(More)
Cerebral nerve activity estimated by means of magnetoencephalography (MEG) is usually evaluated by fusion with anatomical images such as MRI, X-ray CT. Therefore, in order to diagnose using MEG measurement results, it is very important to consider not only accuracy of MEG source estimation but also total accuracy including fusion with these anatomical(More)
We investigated the time course of cortical activity in the brain related to cold epidermal touch stimulation at 4 degree Celsius and touch stimulation at a normal temperature of 14 degree Celsius to the palm of the hand in 20 normal human subjects (average age of 29.1plusmn6.0 years), using magneto-encephalography (MEG). The time course of cortical(More)
