Thank you. I am not a scientist and had only skimmed the published paper, but I read it again properly. It seems that the new magnet shown in this paper showed radio absorption in the 220 gigahertz band of millimeter waves. However, the frequency band of 5G radio waves is much lower, so I don't...

Thanks. I would appreciate it if you could try to translate the page on ChatGPT or DeepL if possible. But I think that would also be a hassle. I was looking for a similar topic in an English-speaking forum or article discussing what I wanted to know...

Thanks for the replies, I will try to get back to you on this one. Oh, I was also writing this topic in the hope of gaining scientific knowledge, but if it is inappropriate, please delete this one as well. I read a post saying that aluminum mesh is not magnetic and iron mesh is magnetic and...

The wavelength of 5G radio waves is smaller than that of 4G, and even a gap of 1 mm or so such as aluminum mesh fabric can slip through, so it is said that attenuation performance cannot be demonstrated. However, I wondered what would happen if the article was made of iron mesh magnetized by a...

I am using an old monitor (MITSUBISHI RDT27IWLM). The power consumption changes when the screen is white or black, but does the frequency of the weak electromagnetic waves emitted from the monitor change? Or is the frequency the same, only the output is stronger/weaker?

Thank you. The hygroscopicity of mortar, which means that moisture adheres to the surface of the walls, may indeed be related to the attenuation of radio waves. Even if I have the bathroom window open, it seems that the moisture clinging to the walls cannot evaporate completely.

Thank you. The bathroom does indeed have high humidity, but based on the comments from the person who conducted the measurements below the image, it mentions that it is natural for the bathroom, surrounded by mortar walls, to have poor signal reception. While the humidity increases when using...

Thank you. I understand that there may be some spatial issues, but the bathroom is not directly above the LAN router; it is located on the same floor. The bathroom is indicated as "Red 65, Blue 66." Japanese can be ambiguous, making it easy for non-native speakers to misinterpret.

If i try to research the details of tile materials, may find out what factors are involved in the attenuation of radio waves by tiles. In foreign movies, I remember seeing exposed pipes in bathrooms, but in Japan, bathrooms typically only have pipes for faucets and showers. The faucets also...

Thank you once again. I see! So even if only a single frequency is emitted, the multipath nulling problem can still occur. I've learned something new. The website where this measurement was conducted is PC Watch, which covers news on IT gadgets and other related topics. They have been conducting...

I was researching multipath nulling since I'm not very familiar with it. It seems that when multiple frequency bands coexist, the signal strength of a specific frequency, even if it is, for example, 100, can be received as 60 due to the multipath nulling function. This is related to the...

I apologize for not mentioning the frequency of the bar graph. The red color represents a frequency of 5GHz, while the blue color represents a frequency of 2.4GHz. Although it is unclear what kind of wireless LAN measurement device was used, it seems that a professional measurement device...

Thank you. It may be worth considering the material of the walls. In Japanese bathrooms, there are tiles, but mortar is also used. Silicon carbide has the property of absorbing electromagnetic waves. Does mortar have such a property as well?

There is a Japanese IT news website that I've been researching about the strength of wireless LAN signals. I would like you to take a look at an image where the attenuation rate of the signal is low only in the area marked as "6," which is the bathroom. Why is the wireless signal strength...

Thank you, I was thinking of putting silicon carbide powder in a water tank and circulating the water in the tank so that the silicon carbide always stays in the cube, but the reply I received says that even a small tornado of silicon carbide does not attenuate the electromagnetic waves that...
