Wireless electronics that have been used thus far in next-generation mobile communications using terahertz waves may reach their technical limit (namely, upper limit of frequency for wireless ...

700-MHz-band “specified” radio microphones are used in music programs, concerts, and the like, but it has become necessary to shift the frequency used by these devices into the 1.2GHz band and the ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...
