Non-transmissive

Non-transmissive describes something that does not allow the passage or conveyance of a substance, energy, or information through it. This can apply to physical materials preventing light or sound, data security protocols blocking information flow, or biological systems hindering the spread of disease. Essentially, it signifies a barrier or blockage, restricting the transmission of something from one point or system to another. Its core meaning emphasizes impermeability or the inability to propagate.

Non-transmissive meaning with examples

• The thick concrete wall was designed to be non-transmissive to both sound and radio waves, providing excellent insulation and shielding for the sensitive equipment inside. This ensured that no external interference could affect the performance of the internal systems, nor could any signals escape.
• Cybersecurity protocols often employ firewalls configured to be non-transmissive to unauthorized data packets. This prevents malicious software from entering the network and protects sensitive information from being stolen or compromised by outside actors or internal threats.
• Certain materials used in medical masks aim to be non-transmissive to airborne pathogens. This blocks the movement of viruses or bacteria, minimizing the risk of infection for both the wearer and those in their vicinity, contributing to public health.
• In cryptography, a non-transmissive cipher would not allow the unauthorized decryption or copying of data, even if intercepted. This makes it very difficult for unauthorized parties to read encrypted messages, preserving the confidentiality of the original data.
