关于我

Be warned: We have kids, born 2011 and 2014. This means early to bed and waking up early.

I can take you skiing or for a walk in the forest. Don't know much about what to do in the city.

我为什么加入 Couchsurfing

All our surfers have been nice, interesting, and decent people. However, about half of those who requested to stay never appeared here, and some of them didn't even bother telling us that their plans have changed. Even though we offer our couch for free, it doesn't mean that you are allowed to 'reserve a room in our hotel' just for backup.

兴趣

Visiting Denmark, I found out that it was very quick to learn Danish based on Swedish. Now I'd like to try to learn more, and also try Norwegian.

The human body acts in a threefold way on an antenna in close proximity: 1) Dielectric loading lowers the resonant frequency and lowers the input impedance. 2) Radiation efficiency is lowered since the human tissue is lossy. 3) The body acts as a reflector and can thus increase the forward gain. You can model the body as a reflector with a reflection coefficient of -0.75.
