Abstract: The acoustically excited antennas based on the piezo-electric effect (PE) have been shown to reduce the size of the long wave communication system transmitter (Tx) to 10 −4 of the wavelength ...

In the global game of nuclear brinksmanship, secrets are the coin of the realm. This was especially true during the Cold War, ...

Abstract: This paper proposes the design method of utilizing mixed couplings theory between resonators with various antenna validations presented and discussed. Due to the mixed couplings excited ...
