Abstract Unidirectional/asymmetric transmission of acoustic/elastic waves has recently been realized by linear structures. Research related to unidirectionality of wave propagation has received intense attention due to potentially transformative and unique wave control applications. However. asymmetric transmission performance in existing devices usually occurs only in a narrow freque... https://www.pomyslnaszycie.com/tillman-750-stick-welding-gloves-sale/
