Thats Good. Defeat door safety switch on microwave oven. Leave door open. Start Oven and place body a few inches from front of oven. Same effect. You are being cooked.
On the whole, a cariage mounted quad-fifty does a more reliable job.
I suggest it is X-Band, 8-12.4 GHz and modulated with square waves, triangular waves,and power swept fast. The feed arms to the feed horn to the refleftor suggest a cp modulation to linear.
Still, anybody hit with 300KW X-band won't need to visit a barber again.
