Greece was eventually occupied by the Nazis who proceeded to administer Athens and Thessaloniki, while other regions of the country were given to Nazi Germany's partners, Fascist Italy and Bulgaria. The occupation brought about terrible hardships for the Greek civilian population. Over 100,000 civilians died of starvation during the winter of 19411942, tens of thousands more died because of reprisals by Nazis and collaborators, the country's economy was ruined and the great majority of Greek Jews were deported and murdered in Nazi concentration camps. The Greek Resistance, one of the most effective resistance movements in Europe fought vehemently against the Nazis and their collaborators. The German occupiers committed numerous atrocities, mass executions, and wholesale slaughter of civilians and destruction of towns and villages in reprisals. In the course of the concerted anti-guerrilla campaign, hundreds of villages were systematically torched and almost 1,000,000 Greeks left homeless. In total, the Germans executed some 21,000 Greeks, the Bulgarians 40,000 and the Italians 9,000.
What civilian group in Greece fought against Nazi occupation?

When an electromagnetic wave strikes a plane surface such as the ground, part of the wave is transmitted into the ground and part of it is reflected, according to the Fresnel coefficients. If the ground is a very good conductor then almost all of the wave is reflected (180 out of phase), whereas a ground modeled as a (lossy) dielectric can absorb a large amount of the wave's power. The power remaining in the reflected wave, and the phase shift upon reflection, strongly depend on the wave's angle of incidence and polarization. The dielectric constant and conductivity (or simply the complex dielectric constant) is dependent on the soil type and is a function of frequency.
What depends on the polarization and waves angle?
power remaining

The BeiDou Navigation Satellite System (BDS, simplified Chinese: ; traditional Chinese: ; pinyin: Beidou weixing daohang xitong) is a Chinese satellite navigation system. It consists of two separate satellite constellations a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.
What is the BeiDou Navigation Satellite System?
