    I Can I send an electromagnetic wave to a specific point?

    Since I'm computer engineer and don't have much experiences with electromagnetism, I'd like to know if it is possible to make an electromagnetic signal (250khz - 500khz) and send it to a point (with an error of maximum 1cm) in a room. If yes which devices do I need to setup my experiment?

    How to transmit a signal (530 - 550 Khz) to a point

    My supervisor want that i have to send signal only to send that points. When the points receive the signal then they are moving. That's mean i only should send the signal to point which i want to move. They have a embedded chip which only listens 530 and 550 khz frequency. So i have no chance to...

    How to transmit a signal (530 - 550 Khz) to a point

    What if i want to send the signal directly from under the table? Will it be possible?

    How to transmit a signal (530 - 550 Khz) to a point

    Hi everyone, I'm pretty new to electromagnetism and have no experiences in this topic. I have a signal generator (Digital Dual Channel Funktion Signal Generator) and want to generate two signals (530 and 550 Khz signal) and want to transmit these generated signals to the points on a table...
