Mikoyan/Gurevich I-320

To meet a requirement for a twin-engined all-weather fighter formulated in January 1948, the MiG OKB proffered the Izdeliye R, a side-by-side two-seat swept-wing fighter with the engines disposed in tandem. Competing with proposals from the Lavochkin and Yakovlev bureaux - all three contenders being awarded three-prototype contracts - the MiG fighter was assigned the official designation I-320. The nose intake fed a plenum chamber around the forward engine compressor, this engine exhausting below the fuselage and a duct leading back to the rear engine which exhausted via an orifice in the extreme tail. Armament comprised two 37mm N-37 cannon, and the first prototype, the R-1 flown on 16 April 1949, was powered by two 2270kg RD-45F engines, whereas the R-2 and R-3 were each powered by paired 2700kg VK-1s. The VK-1-powered prototypes could take-off and cruise on the power of either engine, and the I-320 was initially tested with Torii-A (Thorium-A) radar. This single-antenna radar which demanded manual tracking was succeeded by the basically similar but improved Korshun (Kite) radar with which the I-320 was tested during July-August 1951. Development of the I-320 was discontinued when the requirement to which it had been designed was overtaken by a more advanced one.

It is true that the Russians copied many German aircraft but this is not the case here.The engines in the fwjp045 were side by side below the fuselage.In the MiG I-320 one engine was below the fuselage and the other in the rear fuselage,a completely different layout.

Nope, it's not a copy, it's much bigger and much more advanced. It's influenced though.

It's not a copy since the german design has never existed except on paper. For example, look, the tail unit looks completely different.

The truth is not only Russians used captured german designs for building their new aircraft. The other nations did the same. Just remember the Bell X-5.
